My File system is around 10TB, and now I've got around 1.7TB left, which indicates that Deduplicaiton is not working, or not working they was I would expect it to work comparing it to other products I've used.
How is de-deduplication working? If I create 5 backups of 1TB each, with minimal changes to the 10 VMs between each backup. Would the whole 5 sets of backups be de-duplicated as 1 whole or would the system store 5 backups individually de-deuplicated?
So around 1TB File system used (plus the changes, and any overhead), or 5TB because each backup is treated individually.

How is de-deduplication deduplication working?
If I create 5 backups of 1TB each, each at the source, with minimal changes to the 10 VMs between each backup. Would the whole 5 sets of backups be de-duplicated deduplicated as 1 whole or would the system store 5 backups individually de-deuplicated?deuplicated?
So around less than 1TB File system used (plus used, or 5 x the changes, and any overhead), or 5TB amount because each backup is treated individually.

As a real life example: On the file system for my daily backup for 2 days I can see 2 x 480GB folders, I would have expected the total to be around 500GB (with deduplication and any changes afer 1 day). Instead, I can see multiple folders (1 for each day) at around 480GB.
