How to recover data in from your CVL account
From CVL Wiki
Oops! I deleted some files! Can I get them back?
Files saved on the CVL machines are backed up nightly.
We save a snap shot of your files each day for 31 days. That is, you can recover any file you may have deleted for up to 31 days prior! (If its after 31 days -- don't even bother to ask, its gown...)
If you are logged into one of the CVL machines, there is a directory called "/backup", inside that directory is a directory with the date in it from when that particular snap shot of the files was taken. Under that directory, you will find a directory called "home" and under that directory you will find your home directory (named with your login name) and all of your files as of that date. Is that clear?
Perhaps an example would help.
Suppose today is March 28, and three days ago you deleted a file. The first thing to do, would be to login and go to the /backup directory and take a look. To goto the /backup directory you would type cd /backup, and to take a look at whats there, type ls.
Three days back would be March 25, so we would goto the backup called, Backup.03.Sun_25_Mar_2007_05:07. To do that change to that directory with cd Backup.03.Sun_25_Mar_2007_05:07. (Remember, we have tab completion for long file names. Rather than typing out the whole long name of the directory, just type cd B<TAB>, this completes the name as far as it can: cd Backup.. Now, type the "03" for the third backup and type the tab button again. The computer will finish typing the long name for you!)
