Hi,
I am backing up a Mac computer through ssh/rsync (installed via
Homebrew). Works fine most of the times.
But sometimes the backup does not finish at all. I can see it in the WebUI:
So it is running since 29th of July 13:00. Today is 3rd August, 11:00.
The backup is running for five days!
The Mac went into sleepmode during this time several times if this is
related.
However, this is not an issue of the UI, checking on the shell of my
BackuPC server I can see the processes still runinng:
#pstree -a
[...]
systemd
├─BackupPC /usr/share/backuppc/bin/BackupPC
│ └─BackupPC_dump /usr/share/backuppc/bin/BackupPC_dump macpc.fq.dn
│ └─rsync_bpc --bpc-top-dir /var/lib/backuppc --bpc-host-name
macpc.fq.dn --bpc-share-name /Users/user --bpc-bkup-num 307--bpc-bkup-
│ ├─rsync_bpc --bpc-top-dir /var/lib/backuppc
--bpc-host-name macpc.fq.dn --bpc-share-name /Users/user --bpc-bkup-num
307--bpc-bkup-
│ └─ssh -l user macpc.fq.dn /opt/homebrew/bin/rsync
--server --sender -lHogDtprcxe.iLsfxC --timeout=72000 --numeric-ids .
/Users/user/
[...]
Even on my Mac I can see the matching processes:
|-+= 75087 root sshd-session: user [priv]
| |--- 75088 root <defunct>
| \-+- 75090 user sshd-session: user@notty
| \--= 75091 user /opt/homebrew/bin/rsync --server --sender
-lHogDtprcxe.iLsfxC --timeout=72000 --numeric-ids . /Users/user/
Doing a tcpdump on my Mac shows there is no traffic in between:
% sudo tcpdump host backuppc
tcpdump: data link type PKTAP
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
listening on pktap, link-type PKTAP (Apple DLT_PKTAP), snapshot length
524288 bytes
No packets captured.
So I am wondering why there is no timeout happening. The command line of
rsync seems to have such a parameter.
I can manually stop the currently running backup and start it again
manually- which will run fine.
Anyone having an idea what it wrong here and how I can fix it?
Thanks!
