hi guys,
I am posing a problem that is bothering me a bit.
I have a container running iredmail as mailserver
The disk of this container is 1tb and the total space occupied is about 195gb.
The first backup, with compression, is about 90gb and so far so good.
The incremental backups, the last one of last night copied only 2.4gb of files (compressed 1.2gb), take about 5 hours. is this normal according to you?
All other machines take a few minutes.
The speed appears very low (146Kb/s) while for other CTs and VMs it is much higher.
Could it be that, by copying only single files of the emails, the time for checking and backup is so much and the speed so low?
PBS is on a Proxmox VM with 4 cores and 4 gigs of ram and destination is NFS share.
I attach here the log of the backup of yesterday.
Thank you all for your advice!
