Scheduled snapshots not working #135

Open bittorrenter opened 6 years ago

bittorrenter commented 6 years ago

Hi, The program is a lifesaver, well strictly speaking, a sanity saver.

Unfortunately timeshift (Linux Mint 18.3) is not taking scheduled snapshots - manual backups are working just fine and restore easily. A different machine (Linux Mint 18.1) is taking scheduled snapshots

Regards,

PS there's at least another cup of coffee coming if you can sort this out

Issue is not with Mint 18.3. You need to investigate why it's broken on your system. Some things to check: 1) File timeshift-hourly should be present in /etc/cron.d/ with permissions 0644 and owner as "root". 2) Check if cron is installed and working 3) Check for error messages in system log (/var/log/syslog). Search for "cron" in the file and you will be able to see any messages reported by cron when it executed the task.

Is your system headless? (without a display server installed)

3\. Check for error messages in system log (/var/log/syslog)

@teejee2008 I have found below entry in my timshift log (the program isn't creating any scheduled monthly snapshots for me):

Ubuntu 18.04, headless. The same. Cron backups do not work.

Honestly, I now don't use timeshift anymore and think it is absolutely useless for me. It does nothing above standard rsync, is buggy, consumes disk space. Switched to rsync and zfs replication where available.
