[BackupPC-users] help understanding backup times
Hi,
I inherited a BackupPC system from a previous admin, and admit to not
have used it before.
I'm trying to get a handle on the timing of full and incremental
backups. I've read through the docs but still am not understanding the
odd schedule of backup runs that are going on for my systems. Ideally I
would like to see incrementals done sun-fri and fulls on sat. All
starting about 12:30am each day.
But it seems they're all over the place, with days missed, which I don't
quite understand.
I'm using version 2.1.2.
Here is (what I think) the relevant config variables are that I have
set:
$Conf{WakeupSchedule} = [0.5];
$Conf{MaxBackups} = 2;
$Conf{MaxBackupPCNightlyJobs} = 4;
$Conf{BackupPCNightlyPeriod} = 1;
$Conf{FullPeriod} = 6.97;
$Conf{IncrPeriod} = 0.97;
$Conf{FullKeepCnt} = 4;
$Conf{FullKeepCntMin} = 8;
$Conf{FullAgeMax} = 120;
$Conf{IncrKeepCnt} = 6;
$Conf{IncrKeepCntMin} = 6;
$Conf{IncrAgeMax} = 60;
$Conf{BlackoutPeriods} = [
{
hourBegin = 7.0,
hourEnd = 19.5,
weekDays = [1, 2, 3, 4, 5],
},
];
Here's a recent sample of 1 host's backup runs:
Backup# TypeFilled Start Date Duration/mins
Age/days Server Backup Path
811 fullyes 12/9 11:23 2.3 25.0
/backup2/pc/copper/811
816 fullyes 12/16 11:32 2.7 17.9
/backup2/pc/copper/816
822 fullyes 12/24 11:00 2.1 10.0
/backup2/pc/copper/822
823 incrno 12/26 08:58 0.2 8.1
/backup2/pc/copper/823
824 incrno 12/28 01:44 0.2 6.4
/backup2/pc/copper/824
825 incrno 12/29 03:17 0.3 5.3
/backup2/pc/copper/825
826 incrno 12/31 01:29 0.2 3.4
/backup2/pc/copper/826
827 fullyes 1/1 01:18 2.4 2.4
/backup2/pc/copper/827
828 incrno 1/2 01:15 0.3 1.4
/backup2/pc/copper/828
829 incrno 1/3 01:47 0.2 0.4
/backup2/pc/copper/829
Note no backup on 12/25 or 12/30.
Any help with understanding what's going on, and how I can get it to do
the above that I mentioned would be much appreciated.
Thanx,
-Tony

it's not like traditional tape backup, where you set up a cron job to
initiate each backup at a particular time you choose. the software figures
out what needs to be done, then checks to see if it's allowable.
so if you haven't done a full backup for 7 days (the default), it'll
initiate a full backup next time it runs. It will check about once an hour,
and see if
- there's any job that needs to run
- if there's any blackout that would prevent the job from running
if you're using rsync for your backups (which works the best in most
situations), neither full nor incremental backups transfer all the data on
the machine. (the full backups just do more thorough checks on it). So it's
not that critical to schedule the jobs for a particular time.
I personally have no problem working on my workstation while a full backup
is going on. Then again, I have a dual-CPU linux machine. The Windows task
scheduler is nowhere near as good, and you may be more likely to run into
problems.
But it seems they're all over the place, with days missed, which I don't
quite understand.
if you look at the backuppc logs, you'll probably find that the missed days
were ones where other jobs took up all the available time between the
blackout hours.
you can alleviate this by making per-machine configurations with their own
blackout times (which override the one in config.pl). so for instance it may
happen that the boss doesn't arrive until 10am, and the backup of his
machine takes no more than an hour. you can allow his blackout period to go
as late at 9am (blackouts won't stop a job that's in the middle of running,
just prevent a job from starting). his machine could still be backed up
while others are prevented from doing so.
you may also try upping the number of backups running in parallel; but IME,
$Conf{MaxBackups} = 2 is just about right for LAN backups unless you have
some really high-end hardware. any more and the disk contention kills
performance.
if you insist on having backups done at a particular time on a
particular day; then you can schedule them in cron, using the
BackupPC_serverMesg tool.
# do incremental backups of this machine most every workday at noon
00 12 * * 1,2,3,4 backuppc /usr/share/backuppc/bin/BackupPC_serverMesg \
backup host.example.tld host.example.tld backuppc 0
# do a full backup on fridays
00 12 * * 5 backuppc /usr/share/backuppc/bin/BackupPC_serverMesg \
backup host.example.tld host.example.tld backuppc 1
be warned, trying to force things to happen at particular times can
easily lead to unexpected results, like too many jobs running
simultaneously. also keep in mind that this command won't absolutely force a
job to go off at this time; it's more of a suggestion to the server that it
do this backup now, if possible. I would advise you to do this sparingly.
it is also possible to run a backup job by hand, using the BackupPC_dump
command; but that is dangerous as it can lead to race conditions with some
of the housekeeping processes that BackupPC runs; so only use it for
troubleshooting and debugging.

Re: [BackupPC-users] receiving mails though backup are disabled; obscure time-out error with smb
Renke writes:
First one is that some of our clients aren't online any more but we would
keep
the backups. According to the help I changed the per-client-config of
$Conf{FullPeriod} to -2. Today I get a mail that this machine isn't full
backuped since more than 7 days. I believed the changed configuration would
suppress this messages, has anyone a hint?
I don't believe the messages are suppressed. The reason is you
might use this setting and be using cron or manual backups to
backup the machine. To diable the email you also need to set
$Conf{EMailNotifyOldBackupDays} to a large value.
The second one is real strange. The smb-backup of our Win2000-computers is
stable, but yesterday I added the first XP machine. Now I get everytime the
error Call timed out: server did not respond after 2 milliseconds
opening
remote file \Bin\AdvOCR\F (\Bin\AdvOCR\). On this machine isn't at all a
file
or directory called \Bin\AdvOCR\F but the browsing of the backup-archive
shows
that backuppc creates many empty directories which didn't exists on the
remote
machine.
My first thought was an outdated smb-client but updating didn't fixed the
problem. If I mount the smb-share on the console of the backup-server
everything
is allright and I can't see the directories backuppc tries to save.
The directories are all one-letter names (e.g. a, c, I, N, O, ...) - what
happened?
The 2 millisecond timeout from smbclient is believed to be
caused by anti-virus SW that needs long processing time when the
directory or files are large. Not sure why the error message
doesn't make sense.

Re: [BackupPC-users] Out of memory problem
Steve writes: I'm having trouble backing up localhost, and have traced it down to this: Out of memory during large request for 16781312 bytes, total sbrk() is 354103296 bytes at /d/3/backup/BackupPC/lib/BackupPC/FileZIO.pm line 191. So... I assume that means it choked trying to compress something really big, but I thought ZIO had protections against that sort of thing, and did compression in smaller chunks or something. Is there some way to tweak its handling of expensive compressions, or to get it to note the error and still proceed to back up everything else instead of aborting the backup? Yes, FileZIO does make sure it doesn't use too much memory. It is likely most of the rest of the usage is the entire file list that rsync (and File::RsyncP) keeps in memory. You could add more memory or swap, split the backup into several pieces, or switch to tar for localhost. Craig - Take Surveys. Earn Cash.

Re: [BackupPC-users] OK, how about changing the server's backuppc process niceness?
On 1/2/07, Jason Hughes [EMAIL PROTECTED] wrote: Good recommendations, Holger. I would add that niceing a process only changes its scheduling affinity, but does not modify in any way its hard disk activity or DMA priority, so until the original poster understands what exactly makes the server slow, he's shooting in the dark. A busy hard drive usually makes a system feel slower than a busy CPU process, because hard disk activity requires a 6-10ms seek minimum, plus streaming and unloading to vram, depending on what other processes are doing. Actually, if you are using the cfq IO scheduler in recent Linux kernels, renicing a process also prioritizes IO as well. :-) -Dave - Take Surveys. Earn Cash.
