I have to create a full backup of a storage every day. It’s between 6-8 GB. In the last 2-3 moths I get always high load warning e-mail.
Here is some load example:
Today: The current load average is 7.91 7.22 5.54.
Yesterday: The current load average is 7.78 7.24 5.59.
03/01: The current load average is 7.86 7.23 5.69.
02/28: The current load average is 7.99 7.43 5.71.
Is it normal? If not, what can I do to reduce the server load?
Is it possible to create backup only a selected subdomain and the whole database?
Without taking a much closer look, I don’t really know - If you’d like to open up a support ticket, we can hop in and take a look while a backup’s running to see what’s going on.
If the same backups used to complete w/o driving load up and now do, you may be looking at an i/o issue, and that may mean an issue with raid, if you have a raid set. Degraded raid can cause i/o to degrade as well, obviously.
I’d recommend seeing what’s actually causing the load during the backup.
I changed the backup method to a cron job (backup.pex) as before and I’m waiting for the morning what will be the result.
We’re using raid, it looks like no problem with it. I have a guess, we’re using malware detector that runs in every 5 minutes. Maybe the backup and the detector is too much to our server.
