Over time the number of backups and the storage required to store them will grow. At some point you will want to clean up backups.
To clean up all backups this artisan command can be performed:
php artisan backup-server:cleanup
As mentioned in the installation instructions, we recommend scheduling this command to run daily.
##What happens during cleanup
First, for each separate source, a clean up job to clean up the source will be dispatched. After that, for each separate destination, a clean up job to clean up the destination will be dispatched.
##Cleaning up a source
These steps will be performed when cleaning up a source
- First, all
Backup models that do not have a directory on the filesystem will be deleted.
- Next old backups will be deleted. You can read more on we determine that a backup is "old" in this section.
- All backups that are mark as failed (their backup process didn't complete fully) and are older than a day will be deleted.
- Real backup size will be calculated. Because of the use of hard links in the backup process, the size of a backup will not match the size it actually takes on disk. Here, we are going to calculate what the real disk space usage is for each backup and save it in the
real_size_in_kb on each Backup.
You can increase the default timeout for this calculation with the backup_collection_size_calculation_timeout_in_seconds value in the config file. This may be necessary for large backups, especially if you're backing up to a cloud volume.
##Cleaning up a destination
The package will delete any directory on the destination that does not belong to one of the backups on it.
##Removing a source
When you no longer need to support a source and want to remove all backups, the cleanup command will take care of it.
You can remove the source record in the backup_server_sources table and execute the cleanup job.
