How would you handle file modifications? Backup every original too, or
just deal with literal deletions?

Hi warner,
Thanks for trying :)
Actually my use case was (if you read later replies, i gave up since the
downtime was too long and couldn't wait more) a VM in ESXi.
so all the underlying stuff of the disks/TRIM.. is hidden an
inaccessible for me (hosting provider).
In my case I tried to recover

Do you know what the contents of the file is? At least the first, say, ~32k?
The problem with unrm for ufs is that the directory entry has the inode
number stored in
Just replace rm with a script that moves files to a trash folder, then either
clean that automagically after some period of time or handle it manually.
Doesn’t have to be complicated…

Hi,
thanks for your response.
Would someone from the foundation step in and put it in GSOC ideas?
kirk@ - would it be possible for you to do it ? :)

Hi,
is there anyway easy to restore deleted file by accident in UFS
depends, years ago i had to use sysutils/testdisk to restore files from UFS
after a HD crash.
Using the tools was easy but finding the right data in all the files the tool
restored can be time consuming.

Good luck

A WIBNI (Wouldnt It Be Nice If) for Unix FS's for as long as I can remember
(decades) but
This may help? I’ve no experience with it, I just googled it for you. The
comp.sources.misc usenet group in volume 17 issue 23 (in 1991) has an undelete
program that supposedly works with 4.3BSD — probably won’t work with FreeBSD’s
version but if you’re desperate it could be a starting point.

Use ZFS and snapshots, that should help your use-case.

There should be an os "undelete" as happens in NTFS for example.. which is
very fast and can be done also with extra tools without a hassle.
for now I got backup from last day .. caused me a lot of troubles, not say
legal ones, but I passed the

E.g., grep for something you know (like a phrase, unique name etc) from the
file, then dump N times the expected file size from that position into another
file, open the result in a “robust” text editor and stitch

Depends on the kind of file.
You can always:
1. reboot the system into single user mode, mount the fs readonly (important to
not overwrite data you want to recover)
2. dd the partition and into a file
3. find the content of the deleted file in the dump
I was able to recover a complete codebase

If you used "rm" and didn't take the media offline immediately after, then
no, not only not easy but probably impossible (depending on how active the
FS is)

well.. thats the trivial answer.. the problem is backups is a day before...
if i can undelete it would save me loss of 1 day offset..
anyone?

Yes, restore it from a backup media.
