compare borg to *

[ThomasWaldmann]

there are quite some outdated reviews comparing attic with obnam and other backup sw, but there isn't much out there that includes borgbackup.

write a new one. compare borgbackup latest release to:

• restic
• bup?
• burp?
• rsync?

Stuff to track:

• speed (how long does 1st backup, 2nd backup take? how long does extract take?
• with / without encryption
• without / with fast / with high compression
• how big is the repository? how many files are in the repository?
• does it backup xattrs / acls / bsdflags?
• test with sparse files (VM images are often sparse). Make 1st backup with VM. Start/Stop VM. Make 2nd backup of same VM.

• duplicati (popular under windows, has stable 1.x and a 3-year-in-development 2.0 beta)
• duplicity (used by default by ubuntu with the Déjà Dup frontend)
• rdiff-backup (more sync than backup?)
• SnapRAID (not really a backup solution but maybe worth a mention?)

Plus this like resistance to corruption might be something that can be taken into consideration.

update
Removed non-FOSS and dead projects.

[ThomasWaldmann]

guess only FOSS should be considered.

I added "documentation". Does not necessarily mean it should go into borg docs, but rather that this a documentation-like task.

[ThomasWaldmann]

hmm, it might be nice to have this somehow repeatable or even reproducible.

maybe vagrant and some tests based on pytest-bench(mark) could be used, see also https://github.com/borgbackup/backupdata about how to generate data that is not deduplicatable.

[Abogical]

The Arch Linux Wiki has compared the features of a handful of backup programs (including borg) which would be pretty useful for this task.

[PlasmaPower]

That table looks pretty complete. Anything we would want that isn't on that table? I think just benchmarks. Maybe we could add those (while citing the machine used of course).

That list on the Arch wiki is great (some tools in there I wasn't aware of). It's very detailed.

Although it did strike me that one cool feature of borg that many similar tools lacks is the ability to remove data from the backup repo. The table on the Arch Wiki doesn't have a column for that feature.

[PlasmaPower]

@level323 be the change you see in the world :P

I just tried, but the bot filter for the Arch Wiki signup page requires the applicant to enter the output of an Arch-specific shell command. I don't have any Arch systems on hand to work this out. Change agent: 0. Bot filter: 1.

It seems to be a static question, so...

$ pacman -V|base32|head -1

... should work for you.
