+Backup and Restore
+==================
+endif::manvolnum[]
+
+'vzdump' is an utility to make consistent snapshots of running virtual
+machines (VMs). It basically creates an archive of the VM private
+area, which also includes the VM configuration files. 'vzdump'
+currently supports LXC containers and QemuServer VMs.
+
+There are several ways to provide consistency (option `mode`):
+
+`stop` mode::
+
+Stop the VM during backup. This results in a very long downtime.
+
+`suspend` mode::
+
+For containers, this mode uses rsync to copy the VM to a temporary
+location (see option `--tmpdir`). Then the VM is suspended and a second
+rsync copies changed files. After that, the VM is started (resume)
+again. This results in a minimal downtime, but needs additional space
+to hold the VM copy.
+
+For QemuServer, this mode will suspend the VM, start
+a live backup, and resume the VM.
+
+`snapshot` mode::
+
+For containers, this mode uses the snapshotting facilities of the
+underlying storage. A snapshot will be made of the container volume,
+and the snapshot content will be archived in a tar file.
+
+For QemuServer, this mode will do a live backup similar to the
+`snaphost` mode, but without suspending/resuming the VM.
+
+A technical overview of the Proxmox VE live backup for QemuServer can
+be found online
+https://git.proxmox.com/?p=pve-qemu-kvm.git;a=blob;f=backup.txt[here],
+
+Backup File Names
+-----------------
+
+Newer version of vzdump encodes the virtual machine 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 into the same
+directory. The parameter `maxfiles` can be used to specify the
+maximal number of backups to keep.
+
+Restore
+-------
+
+The resulting archive files can be restored with the following programs.
+
+
+`pct restore`:: Containers restore utility
+
+`qmrestore`:: QemuServer restore utility
+
+For details see the corresponding manual pages.
+
+Configuration
+-------------
+
+Global configuration is stored in '/etc/vzdump.conf'.
+
+ tmpdir: DIR
+ dumpdir: DIR
+ storage: STORAGE_ID
+ mode: snapshot|suspend|stop
+ bwlimit: KBPS
+ ionize: PRI
+ lockwait: MINUTES
+ stopwait: MINUTES
+ size: MB
+ maxfiles: N
+ script: FILENAME
+ exclude-path: PATHLIST
+
+Hook Scripts
+------------
+
+You can specify a hook script with option `--script`. This script is
+called at various phases of the backup process, with parameters
+accordingly set. You can find an example in the documentation
+directory ('vzdump-hook-script.pl').
+
+File Exclusions
+---------------
+
+First, this option is only available for container backups. 'vzdump'
+skips the following files with option `--stdexcludes`
+
+ /var/log/.+
+ /tmp/.+
+ /var/tmp/.+
+ /var/run/.+pid
+
+Or you can manually specify exclude paths, for example:
+
+ # vzdump 777 --exclude-path '/tmp/.+' --exclude-path '/var/tmp/.+'
+
+(only excludes tmp directories)
+
+Configuration files are also stored inside the backup archive
+(`/etc/vzdump/`), and will be correctly restored.
+
+Examples
+--------
+
+Simply dump VM 777 - no snapshot, just archive the VM private area and
+configuration files to the default dump directory (usually
+'/var/liv//vz/dump/').
+
+ # vzdump 777
+
+Use rsync and suspend/resume to create an snapshot (minimal downtime).
+
+ # vzdump 777 --mode suspend
+
+Backup all VMs and send notification mails to root and admin.
+
+ # vzdump --all --mode suspend --mailto root --mailto admin
+
+Use snapshot mode (no downtime).
+
+ # vzdump 777 --dumpdir /mnt/backup --mode snapshot
+
+Backup more than one VM (selectively)
+
+ # vzdump 101 102 103 --mailto root
+
+Backup all VMs excluding VM 101 and 102
+
+ # vzdump --mode suspend --exclude 101,102
+
+Restore a container to a new VM 600
+
+ # pct restore 600 /mnt/backup/vzdump-lxc-777.tar
+
+Restore a Qemu/KVM machine 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 -
