Academic Network Drive
Snapshots allow any user to restore their own deleted or modified files.
- Snapshots are periodic backup records made of all SEASAD user files.
- A snapshot is taken every four hours, starting at 4 a.m daily.
- Once the day is up, the midnight hourly snapshot becomes a nightly snapshot.
- Nightly snapshots cycle into weekly snapshots, therefore files which were on the system on a Sunday night will be retrievable up to a month after they are lost.
