Since few days, when I backup my Containers, I noticed it need more time. Looking better I noticed only one CT take more time to backup:

Code:

Looking even better, for example, I tried to backup a CT107 (I created this container from a restore of a previous backup of CT102, so it's very similar to this latter) and behavior and time is very different:

Code:
[COLOR=#000000][FONT=tahoma]INFO: starting new backup job: vzdump 107 --remove 0 --mode snapshot --compress lzo --storage dev --node srvlive[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]INFO: Starting Backup of VM 107 (openvz)[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]INFO: CTID 107 exist mounted running[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]INFO: status = running[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]INFO: backup mode: snapshot[/FONT][/COLOR]

[COLOR=#000000][FONT=tahoma]INFO: creating archive '/backup/dev/dump/vzdump-openvz-107-2014_10_01-00_44_30.tar.lzo'[/FONT][/COLOR]
[B][COLOR=#000000][FONT=tahoma]INFO: Total bytes written: 843950080 (805MiB, 19MiB/s)[/FONT][/COLOR][/B]
[COLOR=#000000][FONT=tahoma]INFO: archive file size: 384MB[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]INFO: Finished Backup of VM 107 [B](00:00:48)[/B][/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]INFO: Backup job finished successfully[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]TASK OK[/FONT][/COLOR]

I tried to run backup of CT102 in STOP and SUSPEND mode but nothing is changed. I can't understand this. Why this huge difference?
