Another set of snopshots is taken at 12 a.m. every morning and it kept for 7 days.

Disk Backups

We also keep disk backups of all user data. The disk backups run at 12a.m. every night and are kept for 6 months. This allows us to restore data up to 6 months from the current date

Tape Backups

Tape Backups are the third backup resource we have. All user data is backed up monthly and stored for 2 years on tapes. To allow recovery of up to 2 years back. Tape recoveries are much slower compared to disk, but very reliable.

Recovering Data

Recovering data from within the last 1 month:

1. cd to the directory where the file used to reside.
2. cd .backup
3. You should see a list of backups where the name specifies the date the snapshot was taken. The format is as follows: 2010_03_01_23.13.46_America_New_York - This means the file was backed up on March 1st 2010 at 23:13:46.
4. cd into the directory you need, and type ls. You will see the files you need.
5. Directly copy the file into your home directory.
6. Done.

1. Right click the directory where the file used to reside.
2. Select Properties
3. Select the Previous Versions Tab
4. You will see a list of this directory from different dates in the past. You have the option to copy the entire folder to another location or just restore in the place it resides.
5. Done.
