Hi all,

When doing a remote store I'm encountering the following issue:

stefan@MacBook-Pro-van-Stefan _rsyncemm % bup init -r sr@xxx:/home/sr/backups
Reinitialized existing Git repository in /Users/stefan/.bup/ Initialized empty Git repository in /home/sr/backups/

As you can see I can restore the latest, but not a specific branch. Is a known limitation, am I missing something?

Thanks!

Hi Stefan,

Sorry - I left your email open to reply to later, and then evidently
forgot almost completely ..

No, that's pretty odd. I just tried in the context of a test, and I
cannot reproduce this behaviour. That was only with "-r :/path", but
client-side that should result in the same behaviour?

What version of bup were you using?

Interestingly, now I actually reproduced it - on another machine?! I
wonder why this is affected by the machine. Perhaps git versions?

Actually, now I'm confused?

You show ls with just "2021-04-28-101710" but then try to restore "2021-
04-28-101633"?

For me "bup ls" and then "bup restore" with the output works OK - what
*doesn't* work is if I try "bup save -d ..." and then feed that back
directly to restore, that runs into some timezone issues.
