[Duplicity-talk] rdiff during file restoration

[Kirsten]

Hello, all.

I'm in over my head.  If I can just get my data successfully restored -- or, of course, if I can't -- I'll go quietly back to Newbieland.

I'm not sure what happened to make Deja Dup unable to restore my data as requested via GUI.  It has worked seamlessly in the past.  This latest time, though, I just kept being asked for my encryption password, over and over. 

In case it matters, I'm using Ubuntu 13.04 64-bit.  The files to restore were created on Ubuntu 13.04 32-bit.  I did, before anything else, reinstall the 32-bit and try restoring from there, but it made no difference.

I have followed these "Worst Case" directions (bottom of the page), and have, I believe, successfully decrypted and extracted my backup files.  I'm stuck at the rdiff step, due to my general ignorance.  The sources of help that got me this far have dried up.  I hope someone here will help me on what seems to be the final stretch.

Man pages are still pretty inscrutable to me.  http://linux.die.net/man/1/rdiff says that there are three steps to "updating" a file, signature, delta, and patch:

rdiff [options] signature old-file signature-file
rdiff [options] delta signature-file new-file delta-file

rdiff [options] patch basis-file delta-file new-file

I'm not even sure "updating" is what I want, but, given that the Worst Case page says to use rdiff, I'm guessing that this process is for stitching together backup files, which is what I want to do.

I have files of these sorts:

duplicity-full.20130918T163827Z.vol1.difftar
duplicity-full-signatures.20130918T163827Z.sigtar
duplicity-inc.20130918T163827Z.to.20130920T024153Z.manifest
duplicity-inc.20130918T163827Z.to.20130920T024153Z.vol1.difftar
duplicity-new-signatures.20130918T163827Z.to.20130920T024153Z.sigtar

with multiple "full" and "inc" volumes.

I also, as predicted for this stage on the Worst Case page, have "multivol_snapshot" and "snapshot" folders (as well as "multivol_diff" and "diff" folders).

Could someone please show me the code for putting these files back into one piece?  I did post first to the rdiff-backup-users list, but was referred to this list instead.

I would be very grateful indeed for your help.

Thanks.
