Python Backup Cleaner Script
A Python script I’ve written to clean up old backups, keeping only the newest specified amount.
As I covered in a previous post, I am currently backing up my VMs using XSIBackup. There is an option in XSIBackup to delete folders older than N days. This option
--del-dirs however is only available in the Pro version.
So I’ve took it upon myself to script it up, using the available Python 3.5 executable in ESXi and XSIBackups’ built-in cron functionality.
- Copy the script to a datastore
- Edit the xsibackup crontab:
- Add in the script with it’s required options.
-rfor regex and
-kfor how many to keep.

# This crontab belongs to the root user, thus it starts by root- # Add cron jobs to this file in the classic crond Linux way. # This is an example of a backup job being run everyday at 2:00 a.m. # change according to your needs and run ./xsibackup --update-cron # min hour day mon dow command # 0 2 * * * "/vmfs/volumes/datastore1/xsi-dir/jobs/001" 0 4 * * * "/vmfs/volumes/files/Misc/VMs/xsi-dir/jobs/002" 0 6 * * * /bin/python /vmfs/volumes/files/Misc/VMs/clean_backups.py -p '/vmfs/volumes/files/Misc/VMs/' -r 'backup*' -k 5
