1. UGLY 2. you will need to rebuild the mirror once it is reintegrated and thæt is a slow and painful process. 3. you are not guaranteed a stable filesystem of healthy data. ObNote: block-block as backup, and especially "dump" are a bad idea compared to file serializers such as tar and cpio. moreover dump is not supported anymore in kernel 2.4!! other than the fact dump is OS and FS specific, there are apperently major problems with using it on 2.4 with all it's caching features, and I'd imagine journaling filesystems make it even more problematic. read this from Linus: http://old.lwn.net/2001/0503/a/lt-dump.php3 AMANDA warns about this too (scroll to about the middle of the page) http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/amanda/amanda-2/docs/SYSTEM.NOTES ?rev=1.48&content-type=text/vnd.viewcvs-markup -- Born Yesterday Ira Abramov http://ira.abramov.org/email/ This post is encrypted twice with ROT-13.
