Backup Plugin For OMV6

The backup plugin permit to handle everything transparently and automatically at specified time.

It is designed to be simple as possible, to use already existing tools as backend, and to do it as quick as possible.

The backends are:

While this OMV plugin makes backup easy to integrate into openmediavault, based on your settings, the package use software who was created by a third party. See the project / author's

• dd from GNU Coreutils.
• FSArchiver by Francois Dupoux.
• BorgBackup.
• rsync maintained by Wayne Davison.

• OMV-Extras must be pre-installed.

In OMV6's GUI:
Under System, Plugins, find and highlight openmediavault-backup 6.X, and click the install button.

Place Holder

For `ddfull` image, you can use USBImager (Linux, Mac-OS and Windows) or Win32 Disk Imager to restore with a GUI.

They are multiples way to identify your drive or partition, I'm going to explain a few one, fell free to use the one you fell the most confident with.

Remember that you can use the tabulation key to autocomplete path, and the control+c combination to blank your current command. Fell free to try using them beforehand.

Each disk (and partitions) have a different label which is constituted by is connection type (ata, scsi, …), model, serial number and partition number. It is probably the easiest way if you know or can read the label on the top of your drive.

We are going to store it inside a variable for later usage (you can memorize it if you prefer).

SOURCE=/dev/disk/by-id/ata-ST2000DL003-9VT166_5YD2W75Z

If you want to work with partition, and if you know the partition number, you can use the last command and add the partition number directly.

SOURCE=/dev/disk/by-id/ata-ST2000DL003-9VT166_5YD2W75Z-part1

If you don't know it's number, you can list them with `fdisk -l`.

root@omv-dev:~# fdisk -l $SOURCE
Disk /dev/sdb: 50 GiB, 53687091200 bytes, 104857600 sectors
Disk model: Virtual Disk
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 88992846-D209-4046-84ED-1C4DC53ACDC8
 
Device     Start       End   Sectors Size Type
/dev/sdb1   2048 104857566 104855519  50G Linux filesystem

Now you can repeat the previous step but for the target drive.

TARGET=/dev/disk/by-id/ata-ST2000DL003-9VT166_5YD354DB-part2

We create a directory to mount our source first.

mkdir /source

We mount our source

mount $SOURCE /source

Remember again about the tab key for autocompletion.

Move to your folder holding your backup.

cd /source/backup/omvbackup

Double check your command before launching it, after it is launched they're NO WAY TO UNDO IT!

Launch the restore process with the backup of your choice.

zstdcat ./backup-omv-2023-04-23_11-20-11.dd.zst >$TARGET

When the prompt appear again, the copy is complete.

If an error is trow, you can try launching the restore again with dd.

zstdcat /backup-omv-2023-04-23_11-20-11.dd.zst | dd bs=1M iflag=fullblock of=$TARGET status=progress

Some advanced settings can be set by environment variable or in /etc/default/openmediavault.

Please don't use them useless you know what you're doing.
