[aclug-L] Re: Hardware vs. software RAID, etc

[Ryan Hunt <rhunt@xxxxxxxxxxx>]

I will assume, 2 drives = Raid1 and we know raid1 is mirroring

If all you want is mirroring then I wouldent bother with an IDE Raid
Controller (YUK!) I think a software raid would be fine for this
instance..

Instead of raid you might consider the same path I use for mirroring
harddrives.. search freshmeat for a program called "cpbk"
Its a great little tool that compares directories and updates the mirror
drive (via mount) with any files that have updated, added, and deleted..
The best part is a feature called a trashbin, if a file was deleted off the live
drive when cpbk is ran (i run it via cronjob) istead of deleting the
file off the mirror drive,  it copies it to a trash bin for pierodic
manual deletion or recovery...

I dont have any expierence with software raid nor IDE raid tho.. to bad
you cant get him to go SCSI :\

Hope this helps,
:Ryan
