How to change timing of backups

[Ashkaan4]

I have an Ubuntu 22 VM running on TrueNAS. I set up this VM to backup to Proxmox Backup Server. I have no recollection of setting a time. The backup runs every night at 9p. I want to push this to like 2a.

Any ideas how I might have programmed the timing originally??

My crontab looks like this (empty):

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
# You can also override PATH, but by default, newer versions inherit it from the environment
#PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name command to be executed
17 *    * * *    root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *    root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 7    root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *    root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
#

I found this file located at "/root/backup.sh" (obfuscated):

# Variables
export PBS_PASSWORD=<secret>
export PBS_REPOSITORY=<user>@pbs@<ip>:<datastore>

# Command
proxmox-backup-client backup root.pxar:/

# Cleanup
export PBS_PASSWORD=
export PBS_REPOSITORY=

Sometimes the GUI is overwhelming...

First look at Datacenter --> Backup. That is the usual/official place to configure backups.

Then - if you have scripted something yourself - look at the crontabs. There is /etc/cron.d/* for "classic systemwide settings. And then there are "personal" tabs, also for root: try root@xxx:~# crontab -e

Additionally there are "timers" nowadays. Run root@xxxx:~# systemctl list-timers to get an overview.


Have fun
