    Problem with backups. Ever growing dat file.

    This night, all backups went fine. Have to see next night... What I noticed doing the backups manually for each VM, is that it takes a very long time to add each raw file to the backup archive (about 1 hour for a 60 GB file). At the the end, it replaces the old archive. So rsync is not used in...

    Problem with backups. Ever growing dat file.

    This evening, at 19h42 PM, I killed the vzdump process on the host. In the log file file I see this information : Jun 26 02:15:53 INFO: adding '/mnt/vzsnap0/images/107/vm-107-disk-3.raw' to archive ('vm-disk-scsi1.raw') Jun 26 19:42:49 INFO: received signal - terminate process So it began to...

    Problem with backups. Ever growing dat file.

    Yes, it is a compromise between performance and price. You could achieve better performances with fast SAS drives, but with less storage available and a higher cost. With a good raid controller (Perc 5/i and Perc 6/i in these cases), and SATA or Near Line SAS (SATA with SAS interface), in Raid...

    Problem with backups. Ever growing dat file.

    NFS server is a Dell PE2900, and also a cluster node currently (I plan to migrate the VMs there to another server and use it only for backups). The backup storage itself is 4 1 TB SATA drives in Raid 5. Proxmox on this node is installed itself on a Raid 10 volume : hertz:/backup/vm# pveperf CPU...

    Problem with backups. Ever growing dat file.

    Update : last night, backup of VM 107 seems to have failed a few MB before completion : -rw-r--r-- 1 nobody nogroup 997 2010-06-26 02:01 vzdump-qemu-106-2010_06_26-02_00_02.log -rw-r--r-- 1 nobody nogroup 864076288 2010-06-26 02:01 vzdump-qemu-106-2010_06_26-02_00_02.tar -rw-r--r-- 1...

    OK, problem solved. At the end, it produced a tar archive : # cat vzdump-qemu-107-2010_06_25-13_55_50.log jun 25 13:55:50 INFO: Starting Backup of VM 107 (qemu) jun 25 13:55:50 INFO: running jun 25 13:55:50 INFO: status = running jun 25 13:55:50 INFO: backup mode: snapshot jun 25 13:55:50 INFO...

    Problem with backups. Ever growing dat file.

    I think it is apt-get upgrade (not install). I have now : qemu-server: 1.1-15 To test, as I did not want to wait for next backup this night, I copied a part of /etc/cron.d/vzdump, and executed it on the host : vzdump --quiet --node 3 --snapshot --storage hertz_backup 107 But what I see...

    Problem with backups. Ever growing dat file.

    Before someone asks this, I looked in syslog and saw only this for VM 107 : Jun 25 02:01:58 srv-kvm1 vzdump[8631]: INFO: Starting Backup of VM 107 (qemu) And the vzdump processes I see are these : # ps aux |grep vzdump root 8631 0.0 0.0 49392 13668 ? Ss 02:00 0:00...
