Hello good afternoon

Somebody could advise me about the kind of archiving log files that are secure to delete with out brook de harmonic PMG operation?

The /var/log/syslog* is where the tracking center takes it's information from - so if you use that it's probably good to not delete those

/var/log/mail.(log|info|warn) should contain parts of the information that is in syslog too (assuming you did not adapt the rsyslog.conf) - and they seem pretty large - so you can consider them - as always with logfiles - I'd suggest removing the old ones (for example mail.info.1, mail.info.2.gz,...) and keep the current one in place)

apart from that - as a tip for looking where to free diskspace - I can recommend installing `ncdu` (with `apt install ncdu`) and checking with `ncdu -x /`

I hope this helps!

Thanks a lot Stoiko for your advice!

I'm going to take it in mind so acurately, ncdu is a pretty cool tool besides...
