yeah using legacy format, think i may just need to delete everything an start fresh with the new format

in the backup storage tab I don't see the backups like that, its just literally the same file structure as the original data, presuming because I have File Backup not Image Based Backup.

Cloudberry must have a database so it know how many copies of each file it has etc, there must be away for it to run just to clear old copies?

Further to David's reply, i found easier to issue:

dir /a:h C:\Users\John\Desktop
dir /a:s C:\Users\John\Desktop
