Yup. Today I did my (not so) weekly backup and rsynced the repo to the new
drive. After that I wanted to compare performance of my old 3 TB drive and
the new SMR one by deleting a snapshot from the repo on each drive. But Borg
objected on the second deletion, because “the cache was newer”. But that’s
okay. I actually like this, as this will prevent me from chaning two repos
in parallel which would make them incompatible.
