Re: CVS corruption

[Rob Helmer]

Hello,


Well, I don't think "salvaging by hand" would be good or neccessarily effective 
:)
Or easy, for that matter.

For one, depends on the corruption, if it's a hardware or kernel VFS failure
of some kind, and the blocks that the file are on are bad, then there is no
salvaging it, since the data itself will be gone.

If you are lucky, maybe you can pull out the original version, even luckier
if you can get a diff to a newer version. That is unlikely, though.

If some bug in CVS for example screws up the format of the RCS file, you
might be able to save it in this way, but it's not a sure thing. It really
depends on the situation.

As with any data you deem important, make regular backups, and verify your
backups. It's alot easier to restore from backup than it is to go around
manually editing RCS files :)



HTH,
Rob Helmer
