@scottalanmiller correct i stopped the backup process and changed it to daily 2200 HRS backup.. uff thanks scott...
Did that fix the IOWait issue? sar should show it going down in a few minutes.
-
@scottalanmiller
yes
-
Awesome, that was easier than I was guessing that it was going to be.
-
thanks @scottalanmiller
-
Glad that we were able to track that down easily

That's not very much. That should take no time at all. Any idea why it is so slow?
-
@nagendra Okay but what backup are you using? 2 GB per hour is not that bad what we might need to know is the underlying storage and hardware.

Understood.
-
@nagendra Okay are you using any of this?
https://github.com/lucascbeyeler/zmbackup
https://wiki.zimbra.com/wiki/Open_Source_Edition_Backup_ProcedureI use the first link with a slightly modified backup of the mailboxes deleted items since the hot backup doesn't backup those folders (This is the opensource version).
-
@dbeato ohh thanks for the tools i will give a try..
-
If this is a VM server you can also use LVM for snapshots.
-
@dbeato yes its VM .. LVM Snapshot ?? i have option but havent tried it... can we scheduled the backup
-
@nagendra LVM Snapshot are what Volume Shadow Copies are for Windows in Linux. Did you setup your Linux server with an LVM volume?
-
@dbeato yes
