Nagios backups file size =biggun's

Hello all.
When I run
Code: Select all
/usr/local/nagiosxi/scripts/backup_xi.sh script
I run out of space on teh root dir.
I have modified the files to be backed up and added a few directories, but they aren't big. I tried to change the default backup folder to
, which runs fine. I changed the default dir in
Code: Select all
/usr/local/nagiosxi/scripts/restore_xi.sh
to
to but then when I run it fails because the restore script can find the file in
.
So, is there another line or something i need to modify, or is there a way to increase the size of the root "/" not "/root"directory on my machine?
I attached the two files that create the backup that causes the disk space error.
Thanks in advance.
ps. I woulda cracked a coupla jokes, but i am dog tired.

XI backups include the rrds, databases, configs, logs. Think about that for a moment, specifically the rrds. Depending on the number of checks, they may use gigs, if not 10s of gigs in the largest of installs. Logs can also get crazy big. You will probably need to increase the volume size, or backup to an external location (as you were trying). If you are running a vm, you can increase the volume size by following the document below:

All righty bro! Thanks!
On a side note, the restore_xi.sh script does not restore plugins. Is there a reason for that? I mean is backing up the plugins problematic? I wanna know because I want to add the plugins to that backup_xi.sh script.
Sorry man, one more is it possible to increase the size of "/"? right now its using 50gb on a 500gb drive ....I was stupid back then when I set up the server...

So I assume this is not a virtual machine?

Shouldn't hurt anything. Could be that when we wrote the script it was assumed that stock plugins would be used and nothing needs to be backed up.

Probably just fdisk it if a physical machine. If virtual:

Alright, and it looks like you have a giant, unused /home partition. We will have to decrease that as well. This is real sticky business. If it7 is messed up, there is no recover path. Do a full rsync or system back up before trying to do this. I would be partial to helping through a remote session once you have taken the absolutely necessary precautions.
