Project and Home Directory Snapshots

By default each home directory and project directory has .zfs directory that contains snapshots.

Snapshots are backups of your files so you can restore a file changed or accidentally deleted.

This process can impact your quota.  There are some utilities for you as a user to control snapshots

cd to the top level of your project or home directory

touch .nosnapshot -- This will stop new snapshots from being created.  It will still keep your exisiting snapshots

touch .rmsnapshot -- This will remove all of your exisiting snapshots, but will create new ones after that.

You can do both to disable snapshots permanently from your account/project space
