Re: [BackupPC-users] How do you monitor a backup process?

You can follow XferLog with

/usr/share/BackupPC/bin/BackupPC_zcat <pathto>/XferLOG.z | tail

but it is buffered, so not completely current

Also on the backup host, you can get the process id of the current dump processes (there will be two per host during file transfer), and do

(sudo) ls -l /proc/{pid1,pid2}/fd

if a file is being written to backup it will show up in this list. But be aware that there are times (sometimes long) when files are not being written

Hey,

some of the backup processes here run for hours, and there are often
reasons why I want to check on what's going on.

How do you monitor backups in real-time? XferLOG.z can't be tail'd,
and attaching strace or lsof to the running processes just isn't
very sexy.

Can you fathom a good method by which I can keep a good eye on
what's going on, e.g. a way to have BackupPC write to the host's log
file something like

2016-08-04 14:39:11 considering file: /foo/bar/baz (cpool:a/b/c/defgh…)
2016-08-04 14:39:12 skipping file: /foo/bar/baz — already in pool
2016-08-04 14:39:13 transferring file: /foo/bar/baz
2016-08-04 14:39:17 done transferring: /foo/bar/baz

I've tried adding --verbose and --progress to rsync, I've tried
increasing the XferLogLevel beyond 1 (but the XferLOG isn't
real-time in the way I'd seek it).

Maybe one solution would be to write the XferLOG without zlib
compression and only compress it later? Is this somehow
configurable?
