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)

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

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 th

okay...

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.

legal ones, but I passed the p

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

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.

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.

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 ? :)

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…

The problem with unrm for ufs is that the directory entry has the inode
number stored in

so all the underlying stuff of the disks/TRIM.. is hidden an

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