I use rsync as root user. Do you have any idea why files and folders are

Is there any chance that maybe you have mounted a file system in /etc/pve/ and 
call rsync with --one-file-system option?

What is syntax for a second Windows drive?  Apparently "/cygdrive/e/" isn't right; nor is

In Windows by default (administrator can reassign disk letters)
  the 1st logical drive is C:
  the 2nd logical drive is D:
  the 3rd logical drive is E:

I guess, if disk letters are default assigned, the path for the second logical drive

It is easy to draw horizontal lines on the chart, but file system size for

I realize partition sizes rarely change.

Can the size be statically set instead maybe, and changed as needed when the
disk arrays, pools or partitions are increased?


Another option to get file system size is a user-configurable command.


What are some keywords to look for; "rrd add static lines" or some such?BPC

You need to add an HRULE instruction.

They all should be 0 length - they just reference a pool file where

You should use BackupPC_attribPrint utility to get the metadata:

# su -m backuppc -c 'BackupPC_attribPrint

Why do you think the resolution is hourly? It is daily. The RRD step is 
exactly 86400 seconds.




The data may be updated daily, but the resolution of the 4-week graph is 
hourly; the graph is updated hourly,

No. Pictures are generated on page loading.


and each horizontal pixel of the area graph is an hour of time.

No. 4 weeks are 672 hours, but the width of the graph is 600 pixels.


If it were daily I'd only have a one or two pixel wide graph, instead of what I 
have.

Your assumption that pixel resolution always match data resolution is wrong.


The lower (52 week) graph has a resolution of one day.

Actually, both graphs have the same data resolution of one day and both of them 
have different pixel resolution.

I am not trying to convince you if it is good or bad, just explaining what you 
see on the graphs.

You are trying to compare pool size and file system usage, but these are two 
different things. If you want to get the pool size you should use du instead of 
df.

df output should match this numbers:
o Pool file system was recently at 4% (2020-02-27 21:24), today's max 
is 7% (2020-02-27 11:30) and yesterday's max was 1%.
but as you can see, they change during the day. 7% is about a terabyte, btw.

Probably at 01:00 BackupPC was running only for 20 minutes. That is why it was

  o Pool hashing gives 4 repeated files with longest chain 1,
  o Nightly cleanup removed 15 files of size 0.00GB (around 2020-02-27 
01:00),
  o Pool file system was recently at 4% (2020-02-27 21:24), today's max is 
7% (2020-02-27 11:30) and yesterday's max was 1%.

15TB * 0.04 = 0.6TB It is likely that it was correct at that moment.

Actually, on ZFS you are not limited to LZ4, but in ZFS each file block is 
compressed independently, that is why in most cases BackupPC compression is 
higher, though it depends on data.

We moved from 77.96G cpool to pool on compressed filesystem recently. Now it

Craig,

again I return to my issue "No space left on device".

Meanwhile I found the reason: the partition ran out of inodes. As you

May I ask the following:

- in the "General Server Information" you give some statistical
   information about disk usage; would it be a good idea also to give
   information about inode consumption?



It is a really good idea, but obtaining inode consumption with du command is 
complicated since it returns different sets of columns on different OSes.
I think the simplest way is to replace CheckFileSystemUsage subroutine with 
Filesys::DiskSpace module.

Craig, is it ok to introduce another dependency?

On the second thought, skipping certain shares is an overkill. Probably in case

I suggest to create an option in the configuration of the tar xfer method (bool

to abort on Xfer errors or not.


I agree with you. It would be nice to add a configuration option for that, but 
for any xfer type, not only for tar xfer.


The options could be something like:
$Conf{xferErrsAreFatal} If any share had xfer errors then consider the dump bad 
and mark it as partial
0 - no (default)
1 - yes
n - yes if $stat{xferErrCnt} >= n

$Conf{abortOnXferErrs} abort the dump instead of marking it partial if

Hi Alexander,

Thank you for your answer, I am newbie so it was out of my mind to check why 
the xfermethod would be rsync instead of rsyncd for the localhost.

So I changed it to rsyncd. Anyway it won't run .

I set up the rsyncd.conf and create on module :

[boot]
path = /boot
comment = all boot files to be backupc

I didn't put the auth user and password because after some try it say auth 
failure and I prefer to troubelshoot it after resolving this issue

I am not sure what to put in the  $Conf{RsyncShareName} but when I run 
Backuppc-dump -i localhost, there is some errors in the output as you can see 
below.
I printed all the output  and underlined all the errors for more clarity




ERROR: The remote path must start with a module name not a /





I already tried to run rsyncd and it work but I don't know where the error in 
my configuration .

Regards,

Hari




For $Conf{RsyncShareName} you need to use a rsync module name as it is 
specified in the rsyncd.conf in square brackets, i.e. [boot].

$Conf{RsyncShareName} = [
  'boot'
];

Dump is fast because it copies file system blocks. As restore write files, it 
is slow.
You can take dumps relatively fast if you will store the dump in a file instead 
of piping it to restore.
Dump of 60G v3 cpool takes about 2 hours, but restore of this dump takes about 
1 day.

tar -C /var/lib/backuppc --one-filesystem --acls --xattrs -cf - . | tar 

-C /copy -xvf -

How does this deal with hardlinks?

I am running short on ideas how to copy this.


To get rid of hardlinks, consider to upgrade from BackupPC v3 to v4.


This seems to be yet another reason why I want to move this to RAID1 now


Another option is to move to ZFS and use `zfs send` and `zfs receive`.

Probably you still have some V3 backups. It's fine, they will be gradually 
removed one by one at some point during expiration process.
If you really need to get rid of them, you can convert them to V4 backups with 
BackupPC_migrateV3toV4 utility [1].

Why do you need ssh to backup localhost in the first place? You can connect 
directly to rsyncd.

Re: [BackupPC-users] Handle Backup as inconsistent on xfer error

On 1/26/2018 5:31 PM, Zielke, Julian, NLI wrote:

It will be marked as partial but not continuing and/or doing rotation. Also the

series always were open during backup.



Julian, If I understood you correctly, you are trying to solve the following 
problem:
If xfer errors occurred during a backup (files were open or whatever), the 
backup is inconsistent as it misses some files.
In current implementation such a backup is considered successful despite xfer 
errors.
The expiration algorithm dosen't take xfer errors in account as well.
Here is a problem: under certain circumstances BackupPC expiration can leave 
errored backups, but expire consistent ones, so we will be unable to restore 
some files.

That is the reason why I do daily checks for xfer errors and remove backups 
with xfer errors.

Sure, the patch you are proposing will do it automatically, but it seem not a 
good solution to me.
What if something happened with the host's data? In many cases a recent partial 
backup is better than nothing. But you've aborted it!
More over you haven't saved the rest of shares on this host!!! 
https://github.com/backuppc/backuppc/blob/master/bin/BackupPC_dump#L1230
If some files always are open during backup, every backup will be aborted, so 
you will end up with no backups at all.

If we mark the backup as partial instead of aborting it, the partial backup 
will be removed when the next successful backup completes, or if another full 
backup fails resulting in a newer partial backup.
Advantages: files from partial backup can be restored, on the next backup we 
don't need to retransfer files already in the partial backup (for rsync, not 
for tar).

The situation when some files always are open during backup should be avoided, 
in general. In case if there are just a few files and they are always the same, 
it is probably a good idea to create an exclusion list. So if all xfer errors 
happen when attempting to transfer files that are in the exclusion list, do not 
mark that backup as partial.

Do you really want to do this?


Restore to UNC path (Windows share) using rsync is not possible.
In case of rsyncd transfer method, "Restore the files to share" form field means an area 
name like "cDrive", not a windows share name.
You can find the area name in the rsync.conf on the target host.
If you do not have rsyncd on the target host, you can restore to UNC path, but 
you need to use SMB transfer method in this case.

It is updated on every nightly run. It doesn't matter if some files in the pool

In example, if I set the nightly process to scan pool in 2 or 3 days,
graphs would be updated every day anyway, or after 2 or 3 days ?

Asking this because I want daily graphs but as nightly is a very very
very heavy process (load is more than 10 when running) I would like to
split the nightly in 4 days or so.

BackupPC sends notifications if a host has never been backed up or the most

That means you will get an email if backup has never been finished in the 
configured number of days, but BackupPC remains silent if backup was finished 
with a lot of errors.
Some people thinks it's a good thing that BackupPC doesn't bother them if some

I don't know how exactly do this. I guess you need to find files with hardlink

Probably it's not necessary, you just need to wait.

Make sure "$Conf{PoolV3Enabled} = 1;" until the last file deleted from v3 pool.
By default "$Conf{PoolSizeNightlyUpdatePeriod} = 16;". This means you need to

BTW, This section says "You could do this manually". Craig, how'd you suggest

Since your pool is not big you can set $Conf{PoolSizeNightlyUpdatePeriod} = 1;

Also it's not necessary to wait next BackupPC_nightly run. You can start it at 
any time.

I guess something went wrong with migration. Your statistics clearly indicates 
there are files in v3 pool and the latest nightly cleanup removed none of them. 
It looks like these files still used by v3 backups.

`BackupPC_migrateV3toV4 -a -m` should show leftover v3 backups.

BackupPC 3.3.1 doesn't support smbclient 4.x output.
You should upgrade BackupPC to 3.3.2 or downgrade smbclient to 3.6. Replacing 
smb transfer method with rsync would be good choice as well.

`rrdtool create` only relied on umask to create its file. Common case is 640 
backuppc:backuppc.
Probably BackupPC_rrdUpdate (in v4 or distribution patches in v3) should 
enforce the permissions to 644.
I don't know if there are usage scenarios when having graph world readable is 
not desirable. Can this be considered as security issue?

There is no such functionality in BackupPC to send e-mails for job completion, 
but it can send warnings and errors. To configure please refer to 
http://backuppc.sourceforge.net/faq/BackupPC.html#Email-reminders-status-and-messages
 . However, if a backup is not failed, but completed with errors, BackupPC 
doesn't send any warning.
Another option: you can run an external script via cron to get detailed reports 
by e-mail (periodically or conditionally). An example:

BackupPC knows nothing about filesystem block data.

You should send a snapshot of the filesystem where the BackupPC pool resides 
the remote server.
Then you will have an identical filesystem on the receiving side.

root@sending# zfs snapshot -r zpool/fs@2016-10-25
root@receiving# nc -l 8023 | zfs receive -vd zpool
root@sending# zfs send -vRD zpool/fs@2016-10-25 | nc receiving 8023

If you can't trust your environment, use ssh instead of nc.

The RRA keeps updating every day, but with NaNs. This means: 1. backuppc 
successfully writes to RRD, 2. there should be corresponding record in the log, 
3. backuppc cannot get pool size for some reason or broken itself. Do you see 
pool size in WebUI above the graphs?

Permissions are correct, the backuppc user has permission to write. Check 
BackupPC log. Also you can see RRD RRA contents using `rrdtool dump pool.rrd` 
command.

Maybe you find something interesting in the web-server log.

I've seen such an error before, but I don't remember what caused the problem. I 
think CGI returns something else instead of image. If you are lucky it might be 
an error message. Try to save this object as file and inspect its content.

IP addresses in the tag and link don't match (192.168.2.90 != 192.168.15.2). 
Don't you think it's weird?

You didn't mention the problem you have.

Assuming you see image placeholders instead of empty graphs in the CGI:
1. Check current $LogDir and pool.rrd permissions with `ls -l` command. 
pool.rrd should be writable for backuppc user and readable for CGI user 
(commonly the same as backuppc user).
2. Modify the permissions appropriately using chown, chgrp, chmod.

In case you see empty graphs in the CGI after BackupPC installation - there is 
nothing to graph yet. Just wait for 2-3 days.

Your own MTA (Postfix) has accepted test message and put it in mail queue. So, 
notifications are working.

It seems like you mixed up client and server ports. I don't think you should 
use submission port to send notifications - gmail requires authentication for 
MUAs.
I'm afraid, you can't get your own mail server up and running if you don't know 
how SMTP works.

I'm not sure what your question is about, but you cannot specify user name in a 
crontab. Instead of creating a crontab for the root user, create a crontab for 
the backuppc user or use 'su' inside the root's crontab like that:

su -m backuppc -c 'your command here'

It's simple. Just keep data storage (TopDir) on the local file system, i.e. on 
the same host where BackupPC is installed.

In case you don't have separate machine with enough disc space available, I'm 
pretty sure you can install sysutils/backuppc on FreeNAS itself using port or 
package.
But you should figure out a proper way to do that. I mean FreeNAS is an 
appliance, so make sure you won't lose BackupPC and data after FreeNAS upgrade. 
I'm not familiar with FreeNAS, probably you should install ports/packages 
software in a jail.

As FreeBSD sysutils/backuppc port maintainer I can say one of the first thing 
that should be done is to split up configure.pl in two parts: installation 
script and configuration/update script.
It's practically impossible to create pre-built package with monolithic 
configure.pl script, and I didn't find a way to do that. Finally I managed to 
solve that problem applying awful patch to configure.pl that removed 
installation part from it.

Of course it is. Any GitHub user can make pull requests, but only organization

On the other hand v3 and v4 have many identical or very similar code parts. 
Having them as a branches of the same project would simplify synchronous 
changes. I think we will have to support v3 for significant period of time. 
There will be a lot of identical bug fixes. Even minor features would be added 
to both branches.

FUY Both lists somehow mirrored to Backup Central Forums as well.

It's not hijacking, it's a fork and there are good reasons for that. Don't you 
think it might be a good idea to change the project name then and just leave 
the original project intact?

Juergen, thanks for your reminder! I forgot to patch FreeBSD port.
Actually the deprecated defined(@Backups) was already fixed in 3.3.1 and 
4.0.0alpha3 more than year ago. There are records in change logs. But 
unfortunately the patch itself has been lost somehow from the latest 3.3.1 
revision and Craig disappeared.

Is it worth it? BackupPC installation is simple and straight forward, you'll 
have BackupPC_zcat working in a second.

You can manually uncompress particular files with BackupPC_zcat, but you need 
BackupPC installed.

Yes, assuming you have __TOPDIR__ on the USB drive, but if you want to use web

That is.

In BackupPC's terminology it's a "user", not "administrator".

Hosts file header:
hostdhcpuser  moreUsers

It's a local Unix user, and you can't change its email.
You can leave username in the hosts file blank or use mail alias to redirect 
mail wherever you want.

v3: 'full'   shouldn't be expired while there is at least one 'incremental' 
that depends on it
v4: 'filled' shouldn't be expired while there is at least one 'unfilled'
that depends on it

Full/incremental doesn't matter for v4 expiration algorithm since it doesn't 
affect ability to restore particular backup.

I don't think old hardware will be a problem for version 2.

I am using low end hardware for a small mail server (P4 2.80GHz, 2GB RAM, 
gmirror of 2 SATA drives) and BackupPC server (P4 2.80GHz, 1.5GB RAM, SATA 
drive) and 100 Mbps networking.

About 2 years ago I was using Maildir and BPC v3 (rsyncd with checksum caching).
Mail storage had about 100 thousands files.
The first two full backups was completed in about 4 hours each.
Subsequent full backups was taken about 30 minutes (if there is no concurrent 
backups).
I never tried BPC v4 to backup Maildir.

Then I converted mail storage to mdbox + SIS (single instance attachment 
storage) + compression. I never tried BPC with mdbox, I see no point, but I 
believe file list building should be much quicker since file number is 
significantly lower. I installed dovecot (mdbox + SIS + compression) on a test 
machine with similar hardware configuration. Initial backup with "doveadm 
backup" took about 1-3 hours, I don't remember exact time. Subsequent everyday 
backups take about 1-2 minutes and don't depend on mail storage size or 
messages number, but on changes made between backups.

Finally for the backup end I've installed dovecot (mdbox + SIS + compression) 
on a server with ZFS. Now, in order to have retrospective, I'm taking snapshot 
after each backup and using BackupPC-like aging.
And "zfs send" to make offline copies.

Assuming checksum caching configured, for first and second backup, yes. But it 
is not true for subsequent backups since most of Maildir files never change 
over time.

You mentioned earlier you are trying to backup dovecot with Maildir. Do you 
have considered to move from Maildir to mdbox? It will definitely help with 
BackupPC and rsync performance. More over you will be able to use dovecot tools 
(+ your own scripts) or dovecot replication feature instead of rsync/BackupPC. 
It will increase performance dramatically.

You suggestion is reasonable, but any changes in the code or documentation 
isn't possible at the moment. You can find details in the BackupPC-devel

2016-01-10 08:10:48 incr backup started for directory full
2016-01-10 10:27:51 Got fatal error during xfer (rsync_bpc exited with

The incremental backup was interrupted due to fatal error. So, it is "partial". 
It means only some files were backed up.

Looks like your filesystem has been mounted read-only. Check that with the 
'mount' command.

Another question why the filesystem *suddenly* entered a read-only state? Check 
system logs and make sure your HDD is working properly.

Is "file system out of inodes or full" ?
You should check what suggested in the error message: "df, df -i".

Do you have tried to create test hardlinks using 'ls -ld' (with the backuppc 
user credentials)?

Yes, you will be able to use it assuming you synced whole __TOPDIR__ (and 
__CONFDIR__ backup will also be helpful).
But rsyncing a pool that contains a lot of hardlinks will take unacceptable 
very very long time and require a lot of RAM.

You might should consider some block level backup methods, but it depends on 
file system you are using.
For instance for FFS(UFS) dump does the job. I never tried BackupPC on ZFS, but 
I believe 'zfs send' should work too.

That's weird. There is a test in the Ubuntu patch. Images shouldn't appear on 
the page at all if the pool.rrd is unreadable.

Is there anything in the logs?

In this particular case the RRD support is added by third party patch
https://launchpadlibrarian.net/185759725/backuppc_3.3.0-2ubuntu1.diff.gz
Is that correct?

If so, it is not a problem with paths or rrdtool binary since BackupPC is able 
to update the pool.rrd.

Main difference between "update" and "graph" commands: the "update" is running 
by BackupPC daemon and the "graph" by CGI.
Does CGI have permission to read pool.rrd?

But if you removed pool.rrd during reinstall, it is empty now. You have to wait 
2 BackupPC_nightly runs (2 days) until the graphs appear.

Looks like you have a problem with rrdtool or $LogDir/pool.rrd is damaged.

You can do simple tests.
(Replace cd command argument $LogDir with actual path)

$ su
# cd $LogDir
# rrdtool info pool.rrd
# rrdtool dump pool.rrd | more

Commands below should create PNG image /tmp/image.png

"ibs/" is the reversed beginning of the error message you've got.

I think process monitoring is essential if several minutes of hours downtime of 
the daemon is critical, but it not guarantees that all of your data was backed 
up. If you hosts are always on the network may be you better want to know 
backups was successful (or failed) last night instead of process monitoring?

I am agree with Adam in general. Also as a bonus you can track changes in base 
system with BackupPC history.
But you don't want to backup the ports tree, I guess.

Additionally, I always store big volumes of data on separate file system and 
after significant changes in OS I make dumps of all file systems where OS 
resides. In case of disk failure bare metal restore from dump is fast and 
requires almost no efforts.

For FreeBSD hosts I usually exclude that directories:

$Conf{BackupFilesExclude} = {
   '*' = [
 '/cdrom',
 '/dev',
 '/media',
 '/mnt',
 '/proc',
 '/tmp',
 '/usr/obj',
 '/usr/ports',
 '/usr/src',
 '/var/db/portsnap',
 '/var/tmp'
   ]

 environments) - I've recently installed it and started generating some test 
 backups so I can work out any issues, and so far so good.

 However, these are not backup jobs that I would like to keep, I don't see an 
 easy way to delete them through the web interface, so what's the easiest 
 solution (without screwing anything up)?


 If you are going to continue to back up the same content, you won't
 gain much by deleting the test runs since the files are all pooled.
 However, you can simply delete a host's entry under the 'pc' directory
 and delete the host from the backuppc configuration if you no longer
 want that target.  Any pooled files not shared by remaining backups
 will be removed when BackupPC_Nightly runs cleaning out the pool files
 where the link count has gone down to 1.


To remove particular backup:
# cd /path/to/store/pc/hostname
# rm -rf backupnumber
# vi backups  ##remove each line relating to your removed backups

If you do not want to wait scheduled BackupPC_Nightly run, you can start it 
immediately:
# su -m backuppc
 BackupPC_serverMesg BackupPC_nightly run
