Hi all,

I've got an issue with DA backup tool and Centovacast (for streaming audio).
When the backup runs (on a server with around 30-40GB of backups) the streaming via Centova (shoutcast) make small stops now and then until its end 30 minutes later.

Any idea how to sort this out?

Thanks a lot
 
Hello,

Move your Centovacast to a self-standing server then, as DA backup might give a great load on a server in global, and on disk-subsystem in particular case.
 
Then try to analyze
Code: 
top
output in DirectAdmin or shell while backuping and while Centovacast freezes.
Or even post it here.
 
Just an update. I've run the backup script manually and load never goes higher than 2 which is not high on a quad core server with 8GB of RAM.
I've also mount a NFS share and point there the backup and still having the same issue.
I can't troubleshoot this just with top command....if it was that easy I wont posted here!
 
UPDATE: The issue appears only when I'm trying to take the backups remotely. It use all the bandwidth and then make some disconnects on shoutcast.
Any idea if I can limit somehow the transfer of the backup over to ftp/nfs?

Thanks
 
Just run your backups late at night when it doesnt matter.
 
There are connected users 24x7. The only way I can see is via limitation on ftp outbound traffic. Anyone with a good link how to limit the outbound ftp traffic?
 
I've managed to limit the bandwidth but still got issues with server load during backup. It hits just a few times high load during the backup and got disconnects on streaming sources.

Any way to reduce the backup load?

Thanks
 
I assume that I need to add "backup_nice=19" under /usr/local/directadmin/conf/directadmin.conf ,am I right?
Then the backup will automaticall read that conf and assing the related priority?
 
Yes backups will run under nice level of 19 then to not consume as much cpu.
 
backup_nice=19 (default value)

No need to add it in directadmin.conf

Code: 
/usr/local/directadmin/directadmin c | grep ^backup_nice
