How to delete old system snapshot files?

[BigFatGuy]

I have a huge number of files (10tb) located in

/Volume1/@sysSnapShoot/SystemSnapShot

I have verified this by logging into the ssh/telnet and using the DU command.

I'm not currently using any of the backup utilities such as Duple or snapshot, although I played with both for a while, and I found the duple name in several of the files in the snapshot tree.

I have system version 5.1.29. Per the instructions here: (viewtopic.php?t=2350) I logged in using the first account I created on the drive, which should have "root" access.

Many of the files within this SystemShapShot tree, I'm unable to delete using rm and unable to chmod. In all cases, I get an error: "Read-only file system"

sudo -i doesn't seem to work, neither does logging in as root.

I'm unsure how to proceed.

That's because snapshots are protected - for good reason. Not much point having a defence against ransomware if anyone with "root" access can alter the snapshots

@SysSnapShoot files are generated by File system Snapshot found in 'Backup'. If you are running an older version of Tos5, you will probably need to regenerate the filesystem snapshot task(s) as they were and then list and delete snapshots found. (It's slightly easier under the latest Tos version.)

Thank you!

I was looking at the wrong snapshot tool (the one in the app panel), I'd forgotten about the one in the backups panel.

problem solved. Many thanks!
