High CPU wait, I/O and Load Average during backup or outbound migration on Plesk server

    Dinara Tsydenova on my server, backups worked well until ~5 months ago. Since then, the weekly full backup creates a massively high load even though the nice value for backups is set to 19 and the ionice value to 7, and we already disabled backup compression. It feels that there needs to be an additional problem.

    Hi B Pfleging,

    You might be experiencing the bug described in this KB. However, if you see this is not the case, I suggest to open a support ticket with us as further investigation on the server might be necessary.
