Install rdiff-backup for incremental backups
Authored by: rflo on Sep 27, '05 08:22:44AM

Does rdiff-backup handle extended attributes and resource forks, like the -E option in MacOS-10.4's broken rsync, or the --eahfs option in rsyncx? What is the advantage of rdiff-backup over rsyncx?

Not sure of the advantage that rdiff-backup provides over rsync, but it does support HFS+ resource forks and extended attributes. Check here: rdiff-backup Features. Toward the bottom of the page it notes that it does support HFS+.

support of resource forks, access control lists etc.

From the website (http://www.nongnu.org/rdiff-backup/index.html):

"Also features such as Mac OS X resource forks, Extended Attributes, and Access Control Lists have only been released about a year ago [from 2005-09-10]. There are no known bugs in these newer features, but they are not as thoroughly tested as the basic functionality."

Re: benefits over rsync

rdiff-backup uses librsync, but rdiff-backup has the benefit of maintaining a version history. Every time rdiff-backup runs, it keeps track of changes to files and the date/time of the backup. Thus, you can retrieve the latest backup copy of a file, or you can grab a copy of the file as it existed at some other time in the past.

Install rdiff-backup for incremental backups

Maybe I'm missing something, but the version that DarwinPorts installed for me is 0.12.7, which does not have the features you all speak of (resource forks were added in 0.13.0 according to the changelog). So maybe using Fink is a better option (it's unstable package is at 1.0.x I believe). That's what I'm on to try tonight...

Someone made a special patch for rdiff-backup to handle resource forks and whatnot prior to version 0.13.0. I'm pretty sure those were compiled into the DarwinPorts packages because I remember reading it somewhere...

Actually, I just tested this with my DarwinPorts installed rdiff-backup, and NO, IT DOES NOT DO RESOURCE FORKS.

My test was to take a plain bob.html file, copy a new icon to it, verify that a resource fork existed (ls -l bob.html/rsrc), rdiff-backup it up, then restore to another location and the file did not contain the resource fork anymore....

I tried the latest from fink (which turned out to be 0.13.6), but it fails to run with some cryptic errors. Oh well...
