I just started to use this product. It appears to run great at the command
line, however in cron I am seeing the following error in backuplog:

[21/Jun/2005:07:34:24] mv /var/www/hourly.3/ /var/www/hourly.4/
[21/Jun/2005:07:34:24] mv /var/www/hourly.2/ /var/www/hourly.3/

[21/Jun/2005:07:35:01] WARNING: /usr/local/bin/rsnapshot hourly: completed,
but with some warnings

Why did some files only partially transfer during rsync operation? Is there
any way to tell which files? Should I be concerned about this at all?

Hi Michael,

It looks like the warnings came from your /mnt/galileo/userfiles/
directory. I'm guessing (by your other netlogon backup point) that this
is a Samba server. Probably some of your users were modifying files
during the backup.

It should be nothing to worry about. rsync either transfers files
completely, or not at all, so your backups shouldn't be corrupted or
anything.

This also happens a lot on mail servers. The only way to get 100% clean
backups is to kick everyone and everything off the system while they're
happening, which isn't always practical.

If I were you, I'd investigate it, but not lose any sleep over it.

See the other threads recently about rsync output for an explanation of
why it isn't in the log files. If anyone wants to code it, patches are
always welcome :)

Thanks,
-Nathan
