Nextcloud-snap export

backup nextcloud-snap using nextcloud export

• nextcloud export
• compress backup
• move compressed backup
• remove old backups from directory

this works fine as weekly automatic (cronjob as root) job and for random quick backup when needed. compressed backup may be moved wherever.

nextcloud-snap backup may be scripted, see example below

---

rotating nextcloud.export script:

1. create mount directory for media in /media or /mnt

2. mount media using /etc/fstab with option nofail

3. snapshots are kept for 30 days

4. save script in $USER/bin as snapexport.sh

5. set preference variables

6. create root-cronjob for weekly execution ( 0 1 * * 0 su $USER /home/$USER/bin/snapexport.sh )
