BackInTime snapshots fail with path errors

[casanovg]

Backintime stopped working on Fedora 36 as of June 5th, it worked smoothly before. The backup storage I am using is remote, mounting sshfs folders.

The error it returns when launching a snapshot is from rsync (see below). However, I've tried copying directories by hand to remote sshfs folders with several different rsync options and it works fine.

This initially rules out login and connection problems with the backup server. It would give the impression that backintime is "building" the routes wrong before launching the rsync command:

WARNING: Command "rsync -a --delete --rsh=ssh -o ServerAliveInterval=240 -o LogLevel=Error -o IdentityFile=/home/netbackup/.ssh/id_rsa -p 22 /tmp/tmpawvpdq4q/ netbackup@10.6.17.70:"/mnt/hta-nasvol01/hta-backup/backintime/hta-fileserver.htarg.lan/netbackup/10/20220628-091035-792"" returns 3 | rsync: change_dir#3 "/mnt/hta-nasvol01/home/netbackup//"/mnt/hta-nasvol01/hta-backup/backintime/hta-fileserver.htarg.lan/netbackup/10" failed: No such file or directory (2)

Could you include your version of backintime and the version of rsync?

[casanovg]

Sure ...
[netbackup@hta-fileserver ~]$ backintime --version
backintime 1.3.2
[netbackup@hta-fileserver ~]$ rsync --version
rsync version 3.2.4 protocol version 31

Is this a duplicate of #1247 ?

Looks like it. @casanovg, could you test if the workarounds described there help you out for the moment?

Apparently yes, it's the same. Adding "--old-args" as suggested in that thread works again, Thanks!
Sorry to open a new issue, I didn't link it by title because I normally use the BackInTime version packed by Fedora "out-of-the-box". I never update its components (rsync, QT, etc.) individually.

No problem, we're a new, small team trying to sort things out with issues etc. before touching the code and hopefully getting backintime back in shape :) Thanks for reporting!
