undelete

[U.SivaKumar_2]

Hi,
Imagine two situations
Case 1:

I deleted a file from a directory residing in a
single hard disk . How can I recover the file ?

Case 2:

I deleted a file from a direcotry residing in a
AutoRAID box . How can I recover the file ?

regards,

Hi,

I'm very very sorry, but in the unix filesystem there is no utility to do a kind of "undelete" to retrieve the files. Once files are removed it is not possible to get them back.

If you have a backup of this file be happy ;-)

If not, bad luck ;-(

Armin

hi,

I think that your problem is never related to the kind of disk in UNIX, but rather to filesystem structure. Allocated blocks are given back to filesystem free list, not to disk. Try to use fsdb ... not so easy :^)

Hi,

I am aware that there is no utility and it is difficult But I need some tricks like in linux.

As binary file recovery is impossible . I am interested in only text file reovery.

Basically you should have good backups, and then be able to recover from these.
You could also write some form of script to auto-backup or even have a "wrapper" around the vi command that basically copies the file to a backup file BEFOE you edit it. That way, at least you havet he backup if you do remove the origional.

Expanding a bit on Melvyn's editor comments, emacs creates a backup copy of a file when editing. It appends a "~" symbol to the filename. My programmers have them scattered throughout my filesystems - it's a good thing disks are cheap!
