hello @arik 


If you have the option enabled to delete the WAL files after a successful backup, they should not pile up. Instead, Commvault will remove those files once the backup is confirmed as successful.

Hello @Mohamed Ramadan 

Thank you for the answer ,

I meant what happens to the wal files that didnt get archived.

hi @arik , 
I hope you are doing well ,

The WAL files that weren't archived will usually stay on the PostgreSQL DB servers. Commvault processes typically apply to archived backups only, so you can manage the unarchived WALs with PostgreSQL's cleanup tasks. For more details, please refer to this document:
https://www.postgresql.org/docs/current/pgarchivecleanup.html
 

Additionally, if you want everything centralized through Commvault, you can use the “Pre/Post Process” feature to run a Bash script (for Linux) or PowerShell (for Windows).

I hope this helps!
