What happens during archiving?

Question

linux

Here are two days of trouble. Even though no major changes were made.

Answer 1

Well, the graphs show that archiving is in progress.
And what is your problem? The fact that resource consumption has increased after "no special changes have been made."?
So tell us right away about these minor changes, otherwise you can’t see anything particularly strange, archiving has never been a cheap operation.

Answer 2

If the number of the archived processor and the performance of the processor have not changed, the disk subsystem may be degraded. sda - not some kind of raid, by any chance? Maybe the disk has failed or the array is being rebuilt?
Z.Y. - looking at naked LA is pretty useless, use recycling. If iowait grows at the time of archiving, everything will immediately become clear.

Answer 3

When archiving, everything is archived and it consumes CPU and disk resources

Answer 4

Disabled container archiving on Proxmox. Zabiks started screaming about I / O when it started running on Logwatch containers
