rsnapshot logging
Objectives:
- Produce a daily backup summary email (see my post on rsnapreport for details)
- Keep a detailed log file with specific rsync commands showing every file backed up, detailed errors -- well, everything
- Keep logs for a year, but compress to save space (also keep in own dir not to clutter /var/log/)
With the config below, rsnapshot logs commands to be executed to /var/log/rsnapshot/log, it's also told to output specific rsync messages (verbose 5). Crontab entry appends the rsync messages from rsnapshot to the same logfile, so while they're logged without time stamps, each rsync entry is prepended with the time stampted corresponding rsnapshot command, so rsync messages are easy to place.
/etc/rsnapshot.conf:
verbose 5
loglevel 5
logfile /var/log/rsnapshot/log
/etc/crontab:
# rsnapshot backups
00 2 * * * root rsnapshot sync 2>&1|tee -a /var/log/rsnapshot/log|rsnapreport|mail -s"rsnapreport" root
00 3 * * * root rsnapshot daily
45 2 * * 7 root rsnapshot weekly
30 2 1 * * root rsnapshot monthly
Or without sync:
# rsnapshot backups
15 2 * * * root rsnapshot daily 2>&1|tee -a /var/log/rsnapshot/log|rsnapreport|mail -s"rsnapreport" root
30 1 * * 7 root rsnapshot weekly
0 1 1 * * root rsnapshot monthly
/etc/logrotate.d/rsnapshot:
/var/log/rsnapshot/log {
rotate 52
weekly
compress

}

Thanks for your work.
I have set the rsnapshot.conf and logging locations to match your recommendations
First test is an Ubuntu 10.04 server where I am running into the following.
Here is command:
rsnapshot daily 2>&1|tee -a /var/log/rsnapshot/log|rsnapreport.pl|mail -s test myname@domain.ca
And some feedback.

Wondering if you could point me in the right direction?
Thanks in advance,

Hi Michael,
I believe the “uninitialized value” warnings were solved for me by using the latest rsnapshot from upstream (v 1.3.1 at the time I looked at it last) instead of the dated Debian package. Looks like Ubuntu 10.04 also included the same problematic 1.3.0-2 version that Debian Lenny did (see http://packages.ubuntu.com/lucid/rsnapshot).
More info on this a couple of other issues at http://giantdorks.org/alain/rsnapreport-pl-enhancements/
Regards,
Alain

Do you know why rsync errors don’t appear in the log file? I have verbose set to 3 so I see the “No space left on device” rsync error in the console when I run rsnapshot manually, but with loglevel set also to 3, the log just reports “/usr/bin/rsync returned 12 while processing /”. If there’s a way to have the rsync stderr stream appear in the log then that would be very handy to me when things don’t complete successfully.
