There is a manpage with rdiff that explains how to use it. On Debian systems just install the rdiff deb. Be aware though that the 0.9.5 version of rdiff/librsync has a bug that results in larger than necisary delta's. The CVS for the librsync project on SF has a much better version in it. > Moreover, since the synchronization stuff I'm looking for will end into a > perl script, has anybody developed an equivalent of pysync in perl?

I think someone has written a perl interface to librsync... have a search of the rproxy project list archive on SF (the librsync project started as part of the rproxy project). -- -- ABO: finger [EMAIL PROTECTED] for more info, including pgp key -- -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.tuxedo.org/~esr/faqs/smart-questions.html

I know I'm sloppy, but the documentation with rdiff is rather poor. Is there a lengthier explanation somewhere? Moreover, since the synchronization stuff I'm looking for will end into a perl script, has anybody developed an equivalent of pysync in perl? I've found nothing on cpan. -- Franco Bagnoli (franchino) <[EMAIL PROTECTED]> ([EMAIL PROTECTED]) virtual location: Dipartimento di Energetica "S. Stecco" real location: Dip. Matematica Applicata "G.

Is there a better approach? rdiff, part of librsync.

Re: offline rsync
If you can keep two copies of everything, you can use the --write-batch and --read-batch (if they work)... you sync your local mirror, take the batch files to the other system, and apply them to both copies there, then work there. A the end of that run, you sync that sessions changes and take those batch files back. You'll have to get them in sync in the first place, and again if you get them out of sync. You mention zip drives... why not have a drive on each system, and do all your work on one disk? Also, you mention the cost of modem lines... you can't use a regular voice line? How far apart are these two systems, physically? Perhaps an 802.11 with waveguide antennae solution would give you what you a fast, free, mostly secure link.

I though I could produce the "signature" of files on home computer, store it on a zip, go to job, run rsync to copy the missing or altered files on the disk (possibly in zipped form) and produce the new signature file, and repeat it once at home. I think this could also be seen as a backup system (on cdrom or similia). Is this feasible with rsync? Is there a better approach?

Is there a better approach? Rsync itself, no. You could probably build something using librsync (another project). -- J.W.
