ddrescue to the rescue

So two weeks ago my HD did a huge CRACK and it stopped working. The system did not boot up and it just did CRACK CRACK CRACK all the time. So i browsed a bit and saw that ddrescue was a dd variant able to skip failing sectors. So i picked up a new HD the double size of the old one and a RIP CD and started the process of dumping the old filesystem into a file. Two weeks after ddrescue told me i had lost 77MB and thankfully after dumping the file into a newly created filesystem and some fsck later i did not lost anything important.

So thanks a lot ddrescue devels!

Very nice find but no backup?

Sounds like you're in need of a backup solution!

I suggest rdiff-backup ( )

However.... I'm working on an experimental and stupidly simple KDE backup and recovery system based on rdiff-backup. Hopefully it will see the light of day sometime in the near future.

Fantastic! Thanks for the tip.
(I hope I won't use it though ;) )

Thanks for the suggestion.

What gave you the confidence to use this potentially dangerous method, as opposed to sending it to one of those recovery services?

@Backup people: Too tedious, people just do backups after a hardware fail, it gets boring afterwards, though i'm thinking of a RAID setup.

@Jason: I'm not rich and the data was not that critical so a recovery service is not an option, besides Linux tools have always worked for me, so why would i need an "extra" of confidence before using them?
