JSS backups failing (4K files)

[donmontalvo]

Is anyone having problems with JSS backups showing up as 4K? Here's what we're seeing:

The database is currently at 17G. We increased the amount of time between log purges, which is increasing backup size. Hoping to get access to a Syslog server soon.

Could the size be causing errors in backup? If so I can script manual backup of log files and set JSS Setup Utility to purge log files after N days. Was hoping to not go there, so we can get logs over to Syslog server.

Thanks,
Don

Doesn't the xxxM part denote the size?

Tbh, I've not run the command you have below on our JSS, but this is from
the nightly e-mails:

The jssutil (/usr/sbin/jssutil) created a backup of your JSS Database. The
backup was saved to:

/private/var/backups/jss/2010-06-04_03-00-00.sql.gz

The backup is 795M

The follow backups are also present on the server:

792M 2010-06-03_03-00-00.sql.gz 789M 2010-06-02_03-00-00.sql.gz 784M 2010-06-01_03-00-00.sql.gz

Hi Ben,

Yes, I used "h" in the "ls" command to make the sizes human readable. The 20B backups show up as 4K in Finder. Backup sizes have gone up since we disabled automatic purging. We're working on getting a Syslog server built to send JSS logs to. Don't want to lose anything until then.

JAMF suggested that since log deletion defaults to 3AM, we should try to offset Distribution Point replication and JSS backups so they all happen at different times. I made some changes, will see what happens over the next few days. I'll shout back with more news.

Thanks,
Don

Thanks for the explanation.. & no.. We're not seeing them as 40k in size..
I'll likewise let you know if that changes...
