Pre and post backup scripts template for UrBackup client. I tested it with 2.4.10 at debian 10. UrBackup documentation: https://www.urbackup.org/administration_manual.html#x1-330006.4
I use these scripts for stop services before backup and start them back after snapshot creation.
-
Each command is checked for errors;
-
If errors occur during operation, the script breaks, the stopped services will be started services back, then UrBackup backup is not started (Backup had an early error. Deleting partial backup);
-
All events are included in the UrBackup log;
-
Errors are logged in more detail;
- Put these scripts to
/usr/local/etc/urbackupand make them executable; - Make scripts executable
chmod u+x /usr/local/etc/urbackup/functions_prepost_scripts
chmod u+x /usr/local/etc/urbackup/postfilebackup
chmod u+x /usr/local/etc/urbackup/postfileindex
chmod u+x /usr/local/etc/urbackup/prefilebackup
-
Edit prefilebackup, postfileindex, postfilebackup (there are inctructions inside);
-
Create file backup and check log (at the web interface).
-
prefilebackup- UrBackup called before a file backup (before snapshot/shadowcopy creation); -
postfileindex- UrBackup called it after indexing (after snapshot/shadowcopy creation); -
functions_prepost_scripts- functions used by these sripts.
