Good morning,

Since cutting over my servers to CentOS 7, I've noticed an error repeating for one of my nodes whenever it attempts to perform a backup.

Here's the error in the audit log:

System JOBS Wed, 23 Oct 2019 22:05:25 -0700 Error creating LS backup. Check permissions of backup directory /store/backups/nagioslogserver and disk space. 4deb767e-abbd-43f0-8839-049760687e98 Nagios Log Server

When I look at the permissions for that directory, they look okay to me. Also, I think there's enough drive space:

Any ideas why my system is throwing this error?

That all looks good. Are you setup to only keep 5 backups? It may be worth deleting the oldest backup just to see if it's encountering some kind of strange condition where it can't backup because the maximum number of backups has already been reached.

Also, I thought I remembered something about your backups being on a network drive. Was that the case, or was that just the case for your log server data? Because right now it looks like backups are just stored on the local system.

Ok, I'll try that. Where would I find the setting to see how many backups we're keeping?

Our snapshots are written to a network drive. I'm not aware of the backups being written anywhere other than the default location (locally?).

Actually, I am mistaken, it looks like it only keeps 5 backups. I thought it was configurable via System Jobs, but that only changes the schedule.

I would still recommend either deleting the oldest backup, or moving it out of that directory, and seeing if that kicks the backup job into gear.

Speaking of System Jobs, does the Last Run Status of the backups system job show success? Does it error if you run it manually?

This morning it showed FAILURE, but I'll try again now that I've deleted the oldest backup on that particular node.

Ok, the backups worked on all the nodes this time.

Might have been fluke, I would say go ahead and lock this up.

Thanks for the update @rferebee. We'll close this out.
