With VzBorg you can:
VzBorg uses vzdump and BorgBackup to allow deduplicated, compressed backups of Proxmox guests, in an optionally encrypted repository.
For remote backups, you can use your own server, virtual machine, or services like:
You need a proxmox 5.x or 6.x server with a suitable BorgBackup package installed.
If you are running proxmox 6.x you can install BorgBackup with:
apt install borgbackup
If you are running proxmox 5.x you must enable stretch-backports repository:
echo "deb http://ftp.debian.org/debian stretch-backports main" >>/etc/apt/sources.list
Then install BorgBackup from it:
apt update
apt install -t stretch-backports borgbackup
If you want to use a remote repository, you need BorgBackup installed on the remote computer, ideally with the same or a greater version.
If your remote repository is on another proxmox server, you can eventually restore your backups on it. Just install VzBorg, and configure the repository as a local one. Warning: In this situation it is not recommended to use that repository for local backups.
As user root in your Proxmox server run:
wget -O - https://raw.githubusercontent.com/g3492/vzborg/master/install_and_update_vzborg.sh | bash
On first install, a default configuration file with a random passphrase is created.

VzBorg accepts one of the following commands:
| Command | Description |

| Option | Value | Use with commands | Description |
|---|---|---|---|
| -b (--backup) | backup_name | delete/getdump/info/restore | Name of an existing backup (archive) |
| -c (--config) | config_name | all except help/version | Name of a config file in /etc/vzborg dir |
| -d (--dry-run) | purge | Just perform a simulation | |

/etc/vzborg/default
Edit before using VzBorg, to customize defaults values for repository, encryption, etc..
You can have different config files in /etc/vzborg for managing different repositories or environments. You can instruct vzborg to read an additional configuration file with the -c (--config) option. Ex:
vzborg backup -c remoterepo -i 121
Backup guest with ID 121 reading additional configuration file /etc/vzborg/remoterepo.
The vzborg backup command, automatically creates the related borg repository, if it does not exist.
VzBorg creates backups encoding the guest ID and the backup time into the name, for example:
vzborg-104-2020_04_02-17_12_34.tar for an lxc container
or
vzborg-105-2020_04_02-17_15_11.vma for a virtual machine
When recreating a Proxmox backup file (getdump command), VzBorg will use the default PVE naming convention, for example:
vzdump-lxc-104-2020_04_02-17_12_34.tar.lzo for an lxc container
or
vzdump-qemu-105-2020_04_02-17_15_11.vma.lzo for a virtual machine
The best way to start with VzBorg is to edit the /etc/vzborg/default file with some sensible values, and run a back up of a small guest. Then you can try to restore it, backup it again, list, purge, etc.
