Restic restore OpenStack Swift : Slow

Kixz · August 19, 2019, 4:16pm

Hello all,

I’m running restic in version 0.8.3 and i use OpenStack Swift repository .
I’m backing up big file (10G to 100Go per file) and it works great.

But when i try to restore , it’s very slow. about 40-50 Mbits.

I tried to restore file from the Swift repository with another method (python swift client) and i’m going up to 600Mbits

Any idea ?

Thanks.

This is a known restore performance issue. The proposed fix is waiting review&merge https://github.com/restic/restic/pull/2195. You can build restic from the branch yourself to use the fix before it’s merged.

For a feedback:

It works like a charm with the branch : out-of-order-restore-no-progress
Before restore at 50mbits , now restore at 600mbtis
