 Hi,
 
 I've been trying to automate archive (from iSCSI to USB drive) for

 Fridays failed at exactly 1200 minutes in, by a SIGALRM. Is there a time
 limit on archives?
 
 The backups are only 282 GB total (written to USB drive) on a quad core
 xeon with 1.5 GB RAM. Should it be this slow? I do see a lot of CPU time
 in WAIT.
 
 Can I get more than 1 archive running at a time? That is, I have 20

 I want to archive, can I have 4 archive processes running at once, each
 working with 5 different hosts?
 
 Thanks,
 Gerald

I don't know about the hard time limit, but I'm writing about 56GB
(compressed) of archives to firewire drives in ~4 hours. I notice
compression is the limiting factor in my archives, but I'm willing to take
the performance hit to save space as my backups are VERY compressible.

On a quad-core CPU, you should basically be seeing 1 core maxed-out per
archive process since it will be running the compression program (gzip,
bzip, etc) with another one handling the tarcreate process. So, even if
it's possible to run more than 1 archive job at a time (I don't know if it
is) you won't really be able to run more than 2 on a quad-core box before
stalling again on CPU time.

What compression setting are you using? As I said - gzip is definitely the
bottleneck in my archives. Also, if you can get away from USB and switch to
eSATA or fireware you'll see good improvements there. USB is quite a CPU
hog too, in my experience.

Not ... wonderfully.  On the plus side, it does seem to handle the read

As for ownership and permissions, I'm afraid I can't be certain.  On the

preserved or if that happens to be the default.  I'm not doing anything

Check this value in config.pl:
$Conf{ClientTimeout} = 72000;

72000 seconds is 1200 minutes.
What Backuppc version are you running? Newer versions should be less
sensitive to this.

In any case, you can raise this value to some other figure; just watch out
for hung backups not dying.

Re: [BackupPC-users] web interface issues

2010-03-08 Thread Nicholas Hadaway
My problems with backuppc are almost completely solved.  :)
I ran through /etc/BackupPC/config.pl one more time and found some 
misconfiguration.
Take the time to go through that file and get things set right... Even 
if you thought you already set it... double check it...

what really helped the most was pulling out all the comments from the 
config file which allowed for a much more sane view of option settings.

For CSS and pretty stuff:
$Conf{CgiImageDir} = '/var/www/html/BackupPC';
$Conf{CgiImageDirURL} = '/BackupPC';
$Conf{CgiCSSFile} = 'BackupPC_stnd.css';

To make sure you can see ALL hosts when logging in as admin:
$Conf{CgiNavBarAdminAllHosts} = '1';

And probably the most important ones..
$Conf{BackupPCUser} = 'backuppc';
$Conf{TopDir} = '/data/BackupPC';
$Conf{ConfDir} = '/etc/BackupPC';
$Conf{LogDir} = '/var/log/BackupPC';
$Conf{InstallDir} = '/usr/local/BackupPC';
$Conf{CgiDir} = '/var/www/cgi-bin';

I noticed that when I did a re-configure and install of BackupPC to 
re-set my config.pl sanity... I noticed I had to manually populate the 
TopDir, InstallDir, etc... even though the install showed my directory 
structure properly.  Anyway... this is beta release so i'm willing to 
accept things like that...

So the web interface works well after getting the config options set 
properly.

BTW... my OS is CentOS 5.4 + extra repositories to get all the perl 
packages put in nicely.

Next?:  in all this reconfiguration, linux hosts are working 
marvelously... but my windows+rsyncd hosts stopped working... and now 
i'm trying DeltaCopy with the same failures... more to come.

Indeed... thanks for the reminder.

Looking back through my config.pl again as you suggested, I found the options
CgiAdminUserGroup and CgiAdminUsers, helpfully commented that these are the
users who can see the full admin interface.  By default $Conf{CgiAdminUserGroup}
= 'backup', and after my OS reinstall I hadn't get added myself back into the
backup group.  Once I did that, the rest of the admin interface immediately came
back.

Thanks,

Re: [BackupPC-users] Bare Metal Restore for Microsoft Windows XP

2010-03-08 Thread Michael Stowe
 Although I haven't tested it on a bare metal restore, I believe that
 my code that runs subinacl (and also optionally getfacl) to back up
 the Windows ACL's should take care of all file ownership, permissions,
 and ACLs (note that 'getfacl' only captures a subset of the full
 Windows acl's).

Does this happen to include the hidden and system attributes?

 Of course, beyond that there are other potential NTFS 'features' that
 might not get restored such as junctions, alternative data streams,
 etc. -- though typically they are rare in WinXP.

In theory, junctions would be recreated by any hard links in the tar file,
though I didn't have any reason to try it out.

 Thanks for the write-up - very helpful!
 Couple of questions:
 1. Once you have installed cygwin, why not just use rsync to restore
rather than first creating a tar archive?

The main reason is those three hardcoded directory paths -- chiefly
C:\WINDOWS, which tends to have a lot of open files that cannot be
overwritten.  I suppose you could restore those three directories to
alternative locations, but in my experimenting, rsync would throw errors
and stop working, I'm not sure why.

 2. Is the Recovery Console approach necessary? I believe that WinXP
Home bundled by a lot of hardware vendors doesn't include
it. Couldn't you just restore a bare-bones configuration, boot it
up and then proceed as you did

It's included on every XP CD that I'm aware of, including Home, but it
does need to be either installed (for OEM versions, from the \i386
directory) or booted from (some vendors place it on a recovery or tools
partition.)

It's necessary in that I know no other way to replace the windows
directory.

 3. Can you explain the reason for set AllowWildCards = TRUE?
Also, more generally, what if anything is the advantage of using
the MS shell to rename rather than just using cygwin 'mv'? Does
'ren' do a better job with setting default ACL's.

Err...  Whoops, that was supposed to read set AllowAllPaths = TRUE not
WildCards, which doesn't do a lot.

It's required only because otherwise, the Recovery Console won't let you
do anything outside \WINDOWS.

 4. How are you able to rename for example the WINDOWS directory since
it presumably has open files? (or is this the reason and rationale
behind using the recovery console)

That's exactly the reason behind using the Recovery Console.

 5. At what point in the process did you restore the registry or did
you just treat them as regular files that are part of your backuppc
backup?

The registry was backed up as regular files using Volume Shadow Copies,
and restored as regular files into the same locations.  Switching the
\WINDOWS directories switched the registry, as well as all related
files.

 6. Rather than installing cygwin, using the Recovery console etc.,
would it be faster/simpler/safer to boot from a Linux cd/dvd (after
creating the minimalist system install) and then from linux restore
the backuppc shares and rename the directories. Then you could boot
back up (hopefully) in Windows and run subinacl if you want to make
sure the acls's are all correct.

I did try this, and it didn't work -- in my case, because Linux didn't
happen to recognize my controller card, or its metadata for the mirror --
and when I tried it on another system, for reasons I'm uncertain of, it
threw errors with the tar file for some paths, and choked on symbolic
links.  Due to the driver issues, I didn't pursue it further.  (I had
hoped for something relatively simple, like booting to a LiveCD, mounting
the drives using ntfs-3g, and simply rsync'ing the latest recovery; I
assume this is probably possible with the right tweaking and drivers.)

 Thanks again for sharing your experiences...

Re: [BackupPC-users] Bare Metal Restore for Microsoft Windows XP

2010-03-08 Thread John Hudak
Perhaps I missed something in reading this, or my interpretation of a 'bare
metal restore' is different from yours.

My definition of 'bare metal restore' is taking essentially an image of the
current disk, copying it to some media, and then using that image to do a
bit-by-bit (sector-by-sector, track-by-track) copy from the backup medium to
the target medium. For me, the bit by bit copy is primary for the OS, and
possibly including the application programs (word, ppoint, etc.)  I don't
buy into the M$ organization of files and disks.  I partition my hd for OS,
Applications, and User Data. I baremetal restore the OS partition and
usually the Application partition using Acronis True Image. (True Image is
more or less functionally equivalent to Norton Ghost-the enterprise version,
not the butched commercial version they have sold in stores since V9 (I
think)).  I store the images on a NAS that is backed up.
I do restores in one of two ways: Use the restore CD that Acronis allows you
to make-bareboot the machine, the pull the image from a server, or, netboot
the machine, and using an image loader, pull the restore image from the
server and put it on the HD.
Once the target machine is capable of booting the newly restored image, you
can run backup pc (which I gave up on some time ago) or whatever your
favorite backup program is, and copy the backed up user data area to the
target HD.

In your writeup, you talk about reinstalling windows just to get a working
copy of the OS if anything’s installed or working, you’re going to wipe it
all out anyway so why essentially do the install twice?

Your method does allow for the most recent (more or less) snapshot of most
of the relevant windoz files but doing an image every so often would
essentially do the same thing.  In many cases, it may actually be better to
install a clean load image of the OS and apps, rather than restore something
that may be corrupted/virus infected.  In systems where I have this concern,
I have an image of a clean xp + backup program restore that I use. It is all
done over the net, minimal (if any) manual intervention at the target
machine.  If need be, I can also remove the target HD, connect it to the
NAS, then copy the image directly via the SATA/IDE interface, then put the
disk back in the target machine.

Sorry, but I don't see how this method is a baremetal restore with a manual
step in installing windoz. Your still screwing around with loading via CD a
copy of XP, and then cgwin, and then 'manually copying' files in the XP
subdirectories.  Seems like a lot of places for things to fall through the
cracks with file contents not being 'in synch' and I also wonder about
registry consistency and backup.

It may, however, work fine in your environment.

Re: [BackupPC-users] Bare Metal Restore for Microsoft Windows XP

2010-03-08 Thread Michael Stowe
 Perhaps I missed something in reading this, or my interpretation of a
 'bare metal restore' is different from yours.

I use the term bare metal in the sense that when the process is started,
there is no software or operating system installed.  In other words, I'm
talking about the system being bare metal, not BackupPC being a bare
metal restore imaging program.

 My definition of 'bare metal restore' is taking essentially an image of
 the
 current disk, copying it to some media, and then using that image to do a
 bit-by-bit (sector-by-sector, track-by-track) copy from the backup medium
 to

 Once the target machine is capable of booting the newly restored image,
 you
 can run backup pc (which I gave up on some time ago) or whatever your
 favorite backup program is, and copy the backed up user data area to the
 target HD.

I'm not really advocating that people start *planning* on recovering full
operating systems using nothing but BackupPC, I'm only suggesting that
it's possible if that's all you happen to have.

 In your writeup, you talk about reinstalling windows just to get a working
 copy of the OS if anything’s installed or working, you’re going to wipe
 it all out anyway so why essentially do the install twice?

1) Because BackupPC doesn't have a LiveCD that does recoveries
2) Because Windows XP has never had a LiveCD
3) Because you still need boot sectors, even if either 1 or 2 were true

The technique as outlined does allow you to recover on pretty much any
hardware that Microsoft XP supports, which includes raid cards,
proprietary metadata and exotic controllers.

Note that the entire registry is recovered as well.

 Your method does allow for the most recent (more or less) snapshot of most
 of the relevant windoz files but doing an image every so often would
 essentially do the same thing.

To clarify a bit:  it allows for 100% of the files to be recovered, but
permissions/owners/flags are not fully preserved.

 In many cases, it may actually be better
 to install a clean load image of the OS and apps, rather than restore
 something that may be corrupted/virus infected.

I'm also not advocating this recovery method in all cases (obviously.)

 In systems where I have this
 concern,
 I have an image of a clean xp + backup program restore that I use. It is
 all
 done over the net, minimal (if any) manual intervention at the target
 machine.  If need be, I can also remove the target HD, connect it to the
 NAS, then copy the image directly via the SATA/IDE interface, then put the
 disk back in the target machine.

I have something similar, it's just not always the best choice.  Note that
I've also documented extracting specific registry keys from BackupPC
backups in cases where you need to retrieve, for example, an installation
key.

 Sorry, but I don't see how this method is a baremetal restore with a
 manual step in installing windoz. Your still screwing around with loading
 via CD a copy of XP, and then cgwin, and then 'manually copying' files in
 the XP subdirectories.  Seems like a lot of places for things to fall
 through the cracks with file contents not being 'in synch' and I also
 wonder about registry consistency and backup.

As I mentioned, one starts with bare metal -- it's not an unattended bare
metal restore.

As I documented, there are three directories that need to be renamed (six
if you count the ones you're replacing.)  The registry is perfectly intact
and consistent; naturally this requires one of the rsync/VSS methods that
have been outlined here before.  As, frankly, is every other file, which
includes databases, Outlook, and so on.  (It does highlight the need to
use rsync/VSS and not just use rsync or SMB.)

 It may, however, work fine in your environment.
 -J

I expect it to work as documented in anybody's environment, with the
quirks and limitations outlined.  Whether or not somebody can live with
that certainly depends on their environment.

As I've mentioned, I don't think I'd plan on this being my only recovery
method, but it's worth documenting because it does actually work, and I've
been around long enough to know that it's not unusual for

Technically, it allows for 100% of the files to be recovered that
cygwin rsync/tar or smb can see. There are ntfs files that won't be

be *lost* since cygwin explicitly doesn't handle such non-POSIX

You're quite correct, and I forgot all about them.  In XP, I -think- they
contain thumbnails, author and title attributes, and whether files were
downloaded from the Internet.  A quick check demonstrates that zip files
that were downloaded and backed up are no longer marked as such after the
recovery, but the files have the exact same md5 sum (indicating that only
the main fork is considered.)

Of course, they can also be created manually as well, though I'm not aware
of any software that makes use of them for legitimate purposes.  (I'm
aware of a few viruses that use them to hide chunks of code.)

I guess it's not a big deal for my XP systems, but I suspect this could be
a big problem...  I'm not sure if Microsoft has increased the use of ADS
for Vista and Windows 7.

I did make a quick test for junctions, and they -appear- to work, but this
might just be reflexive since I used a cygwin hard link to create the
junction in the first place.

Re: [BackupPC-users] Backups no longer run automatically

 I noticed this morning that my backups had not run over the weekend. They
 are supposed to be automated and run every day. A full backup runs weekly.
 Incremental backups run every night or day. Friday, Saturday, and Sunday
 backups were all missed. This was for every single computer.
 
 I'm naturally wondering what changed. I have run the backups manually.
 However, this is definitely not a good solution. Backups run manually just
 fine. I rebooted my server, and this did not fix the problem.
 
 The only change that comes to mind is that I did one new PC to the backup
 server last Friday. I have not changed any other setting.
 
 Some backups are scheduled to run only at night. Other backups can run
 anytime.

Usually this means that your pool filesystem is 95% full (or wherever you've 
configured it to not start backups).
