Are these all features of ext3? If so, wouldn't dump do the job?
Well, it's not quite the same thing. You can't safely dump a live filesystem, making it unusable for me. Also it's far less granular than an archiver like tar or dar.
LVM snapshots will allow dump to be used on live file systems.
Dump does not work across file systems, so if you want to convert an Ext3 file system to ReiserFS or XFS then dump will not help.
Dump is tied to Inode numbers and I believe that this has some implications for restoring deleted files if the machine has continued operation and created other files with the same Inode numbers.
We do need a better backup solution, a friend investigated backups some time ago (without regard to SE Linux) and reached the conclusion that extending "dar" offered the best promise of all the Linux backup options. So dar may be worth considering.
Has anyone looked into bacula's ability to store extended attributes? Does it have any?
