Re: Recover deleted FFS files

[Dan LaBell <dan4l-nospam%verizon.net@localhost>]

Recover from logical backup, if possible.
I was just imagining how management might prefer a candidate who  
favors a RAID solution, simply because recovery or partial recovery  
of backup, is known to be impossible, so that conversation doesn't  
have to happen, every time,
something is deleted, or added.
Easy recovery from mistaken deletion, is actually bad, for a  
filesystem that is shared with many humans.
In the future, use a tool to delete, instead, maybe, one that makes  
use of snapshots.
Here's link to a tool, that simply, asks me, the questions, I know, I  
need to ask myself, to avoid stupid mistakes.

Inadvertent example of use:

:untitled folder>:pwd
/Users/daniel/untitled folder

0:untitled folder>:cd ..
0:daniel>:remove untitled\ folder/
D 755  102b untitled folder/
Delete 1 file? y
remove: untitled folder/ : Directory not empty
Performed 0 deletion.
1:daniel>:cd untitled\ folder/
0:untitled folder>:ll
0:untitled folder>:ls -l
0:untitled folder>:ls -a
.               ..              .DS_Store
0:untitled folder>:rm .DS_Store
0:untitled folder>:cd ..
0:daniel>:remove untitled\ folder
D 755   68b untitled folder
