No request for help, just some positive feedback:
As my backup disk ran out of space, I just convinced myself to upgrade from the restic version shipped with my distribution to the latest stable release.
I then enabled compression on the repository and recompressed all packs with maximum compression.
The backed up system is my main work machine, where I do lots of software development, have some databases stored, but also a bunch of less compressible office documents (already zipped internally) and media files.
These were the results:
==> restic_v1_size.txt <== 1,9T restic/ ==> restic_v2_size_1_after_conversion.txt <== 1,9T restic/ ==> restic_v2_size_2_with_compression.txt <== 971G restic/
There was probably some unused data in the packs before the recompression, however at most 100G.
So repository compression is really a HUGE win for actual real world cases, not just for specifically tuned benchmark situations.
That’s really great, thanks a lot for the great feature and the continuous and consistent work on restic!
