Update: Copy succeeded.
$ restic stats --mode raw-data
repository xxxxxx opened (version 2, compression level auto)

Total Uncompressed Size: 7.751 GiB
Total Size: 7.454 GiB
Compression Progress: 100.00%
Compression Ratio: 1.04x
Compression Space Saving: 3.83%
On B2 web interface: old repo 8.8GB vs new repo: 8GB (don’t know if it’s good enough for compression max). Strange that compression level auto sneaked in (maybe this). restic copy was done with --compression max
Some notes (just in case it helps someone else):
-
--dry-rundidn’t work either withinitorcopy(not sure I missed something or that’s how it is) -
During first copy attempt the command was interrupted; succeeded in next try. But the new repo had ballooned to 17GB (vs 8GB of old repo).
restic checksaid……additional files were found in the repo, which likely contain duplicate data…→restic prunefixed it. -
restic check,restic check --read-data-subset=1/20, andrestic restore(checked on couple of smaller file/folders) passed.
I will check with --read-data later, set up backrest, and then delete old repo.
Thank you @kapitainsky and restic community.
