How can I force Vorta to use zstd,10 or zstd,15 ?

[amski1]

I added the --compression zstd,10 to the Extra arguments / Additional Borg options and it did nothing. Htop still showed zstd,8 being used. Any way to change this reliably? Zstd,8 is too low for my needs.

Additional info:
Vorta 0.8.12
Borg 1.2.8
Mint 22

I believe this settings is done via a dropdown and you can't change it.

For the reasoning of each option see the source code comments.

So, the way I understood this, is that I can add compression options to the "repo_tab.py" file in the source code and build Vorta?

I see these two in there:

self.repoCompression.addItem(self.tr('Zstandard Level 3 (modern)'), 'zstd,3')
self.repoCompression.addItem(self.tr('Zstandard Level 8 (modern)'), 'zstd,8')

If I add my own algo's, like zstd,10, will it build with these options in the menu choices?

Yeah, you can adjust the code and the options you need there.

No PR for this please, since the Borg author himself suggested those options and we aren't looking to change them currently.
