Hi Folks,
I'm trying to retrieve some deleted files from a BackUpPC backup. The
backup was deleted, but not much has been written to the drive since the
backup. This is an ext3 file system, so I'm forced to use the grep an
unmounted drive method of retrieval.
Does anyone know a way to have grep return everything between two retrived
strings? Like everything between "tuxpaint" and "end". I'm trying to
retrieve PNG files. Can you describe to me the tools and syntaxes I'd
need to employ to accomplish such a feat? I'm familiar with the command
line, I've gotten grep to return some interesting results and I know about
piping commands, but I can't quite figure out the steps to extract these
pngs from the raw hard drive.
instead of grep, how about the command:
perl -ne 'print if /tuxpaint/../end/'
That would be a filter to print the lines from the one matching the
regexp /tuxpaint/ to the one matching /end/.
It'll work as a filter like grep does; either specify filenames at the
end of the command line or pipe something into it.
Are you searching backuppc's ext3 filesystem? Those PNG backup files
are likely compressed with backuppc and gzip, so you're really wanting
to look for backuppc's header information. Also, realize that
sufficiently large files will not necessarily be contiguous on the
unmounted drive.
Here's a thread where someone had some limited success with midnight
commander in 2002....
