Borg Backup Ubuntu on WSL2
Daniel Nashed – 14 June 2020 16:57:55
Some really cool software isn't available for Windows.
BorgBackup -> https://borgbackup.readthedocs.io is on my list for very efficient backup.
I have tested it a while ago with my Domino Backup application. It's a bit more difficult for backing up one database after another.
But for backup of my source code and related files, this is a perfect match.
Already when playing with NSF backup the results for compression and deduplication have been amazing!
I can further optimize it removing or excluding binaries and objects. But this already looks great!
BorgBackup can use remote repositories. So I can send the data over SSH to a Linux machine.
And I could still use another backup tool to backup that repository. Actually I would probably use more than one repository.
Install BorgBackup
Sadly BorgBackup isn't included in the Ubuntu distribution for WSL2.
But you can download borg_linux64 and just use it.
https://github.com/borgbackup/borg/releases
BorgBackup is definitely a great tool to look into, if you are running on Linux!
See my backup results below from the first and second run today.
/mnt/n is my drive n: automatically mounted by WSL inside Ubuntu.
Because my source code directories will not change a lot, this is great incremental backup.
But it also worked well with Domino NSF if you have the right storage optimization strategy.
If you use DBMT with 10% pre-alloc and a compact not more than every 2 weeks, you should have a quite good deduplication rate
(assumed you have DAOS, NIFNSF and other storage optimization in place.
Here are some stats from my source code directories.
