how to free up space without deleting snapshots
Hi!
I have a Readynas 102 with OS "Version 6.10.2" running on it.
2 x 2TB disks redundant with Raid 1 (X-Raid enabled) (screen attached), snapshots on with 6 years of protection.
I recently noticed that we have 500GB of unnecessary data (raw videos) on it, what we won't need in the future. (No need to have it on the snapshots or in any form.).
It's not a full share, it's only 1 directory inside a share.
I deleted the unwanted directory, but i don't see any space freed up, and i also can't see any space reserved for snapshots shown. (Screen attached.)
How could i get rid of that directory without deleting the snapshots. (Because i don't want to lose the snapshots about the other directories inside the share.)
Is there any way to access the redundant(backup) disc and delete the unwanted directory from there, or from the snapshots?
Thanks for the help.

Snapshots cover the entire share, there is no way to exclude specific folder from the snapshots. There is also no way to delete anything from existing snapshots.
You can try doing a balance, and see if that frees up any space. But the videos will remain in the snapshots for the share.

The two disks are mirrored - everything written to the data volume is written in parallel to both disks. There is no way to change that.
There are plenty of situations where data can be lost, even with RAID redundancy. RAID just isn't enough to keep your data safe - you need to have a separate backup for that. Backing up to a USB disk is one popular way to do that.
Thanks for the fast answer.
Sorry for "backup" expression, i meant the mirror disc as you understood it good. :)
Backup is not a problem, i also have daily backups to another (older) nas.
I used to have the quota checkbox checked, now i turned it off, and also balanced the disks but no more space available then.
I don't understand that how can't i see the used space for snapshots, just the "available space and used space" unless i deleted 30% of the used space by those raw videos. Those should be only in the "snapshots".
But i see the same "1,2TB" used and no space indicated for snapshots as before deleting those.
