Frequently ask yourself: "How upset would I be if I lost all the work I did since my last backup?"
Many of the ECE accounts are hosted and served by our NetApp FAS 270. One very nice feature of the NetApp is called Snapshots. Approximately four times per 24 hour period, the NetApp will look at files that may have been changed or modified since the last scheduled time. If a file has been changed or modified, a copy of it is created and placed in a special directory called "~/.snapshot". These files are not held for very long, and it can often be as short as two days. The benefit is that if you inadvertently delete a file or if you quickly realize that you really need a file that you recently deleted, you may be able to get it back.
While most people's accounts are hosted on the NetApp, there are a few accounts that exist on other servers in ECE. To find out if your account is hosted on the NetApp and can take advantage of the Snapshot backups, log into any ECE department Unix machine and type "homehost" at the command line prompt. If it returns "plum" as a response, your account is hosted on the NetApp.
For information about how to recover files from Snapshots, please refer to the ECE Snapshot Computer Support page
