Re: [PLUG] CentOS backup options


What's the CPU overhead for diffing two 10Gb files to get the 5Mb output?

I'd heartily recommend rdiff-backup.  It's similar to rsnapshot, but instead 
of making copies of changed files, it uses binary diffs.  Suppose you make a 
5MB change to a 10GB file, rsnapshot will use 10GB for another copy of the 
file, whereas rdiff-backup will only use about 5MB for the changes.  It 
supports SELinux via pyxattr, as well as POSIX ACLs and Mac OS resource 
forks.
