Hello,
Using restic v0.9.4 under Windows 10 Pro, with a repo stored on an external USB hard drive, if I check
the repo it’s really fast (under 5 minutes), while adding --read-data
it’s very slow (around 7 GBytes per hour).
However, as --read-data
recursively checks the SHA-256 of every file in the data/
directory, and using an external tool to verify the SHA-256 of that directory is much faster (around 20 times faster) than running restic -r repo check --read-data
, my question is, would these two operations be equivalent?:
- Run
restic -r repo check
and then, verify (with an external tool) the SHA-256 of the files underdata/
- Run
restic -r repo check --read-data
If not, what else is --read-data
doing above a simple check
and then SHA-256(data/
)?
Thank you.
