Google it.
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. -- Grüße | Greetings | Qapla’ Please do not share anything from, with or about me on any social network.
