Useful Proxmox Commands & Links Backup File Names Newer versions of vzdump encode the guest type and the backup time into the filename, for example vzdump-lxc-105-2009_10_09-11_04_43.tar That way it is possible to store several backup in the same directory. The parameter maxfiles can be used to specify the maximum number of backups to keep. Restore The resulting archive files can be restored with the following programs. pct restore Container restore utility qmrestore QemuServer restore utility Examples Simply dump guest 777 – no snapshot, just archive the guest private area and configuration files to the default dump directory (usually /var/lib/vz/dump/). # vzdump 777 Use rsync and suspend/resume to create a snapshot (minimal downtime). # vzdump 777 --mode suspend Backup all guest systems and send notification mails to root and admin. # vzdump --all --mode suspend --mailto root --mailto admin Use snapshot mode (no downtime) and non-default dump directory. # vzdump 777 --dumpdir /mnt/backup --mode snapshot Backup more than one guest (selectively) # vzdump 101 102 103 --mailto root Backup all guests excluding 101 and 102 # vzdump --mode suspend --exclude 101,102 Restore a container to a new CT 600 # pct restore 600 /mnt/backup/vzdump-lxc-777.tar Restore a QemuServer VM to VM 601 # qmrestore /mnt/backup/vzdump-qemu-888.vma 601 Clone an existing container 101 to a new container 300 with a 4GB root file system, using pipes # vzdump 101 --stdout | pct restore --rootfs 4 300 - Command to list the running VPSs in a node # vzlist Command to list running and stopped VPSs in an node.
