Oops! I deleted some files! Can I get them back?

  • Files saved on the CVL machines are backed up nightly. You can recover any file deleted up to 31 days prior.

How to Retrieve Lost Data

1. Log into the CVL machines.

2. Look for the directory called "/backup".

3. Look for the directory with the date in the name.

  • The date reflects when that particular snap shot of the files was taken.

4. Look under that directory and find a directory called "home" .

5. Look under that directory where you will find your home directory (named with your login name) and all of your files as of that date.



(fg.1) The "/backup" directory.
(fg.2) The "/backup/Backup.03.Sun_25_Mar_2007_05:07/home directory.

Still Having Issues?

  • Here's an example:
  • Suppose today is March 28, and three days ago you deleted a file.
1. First, login.
2. Go to the backup directory.
  • To go to the backup directory type cd / backup .
3. Once in the backup directory type ls .
4. See figure 1.
  • Three days back would be March 25.
5. Go to the backup called: Backup.03.Sun_25_Mar_2007_05:07.
6. See figure 2.
Note: Remember, we have tab completion for long file names.
  • Rather than type out the long name of the directory, just type cd B<TAB>.
  • This completes the name as far as it can: cd Backup.
7. Type the 03 for the third backup and type the tab button again.
  • The computer will finish typing the long name for you: cd Backup.03.Sun_25_Mar_2007_05:07
8. Once in the directory Type: cd Home
9. Go to your files.
10. Type: cd <login_name> .
11. Type ls.
  • You will see your files in the same state that they were when the backup was done.
12. Find your file.
13. Copy it to your home directory.
  • The easist way to do this is type something like cp <file> /home/<login_name>.
