If you do the following: 1. Take a snapshot of the system after installing and configuring everything. 2. Make good backups of /home and (for Samba /etc/samba) then you can get back up and running en very little time. I take periodic snapshots of servers when I get a chance to restart them (like after a kernel update scheduled for after hours. Takes me a couple of minutes to make a tarball of the / partition and regular bakcups take care of /home and databases. Thanks to the kind of unstable power around here that can blow a UPS and everything on it in one go, I've had to recover whole servers a few times. Above recipy works every time. As for software v.s. hardware, for a simple raid-1 I find software good enough but only if cost is really a huge factor. If I do Raid-5 I insist on a raid card. Adaptec 2410SA PCI SATA (and the SCSI equivalent) has served me very well. Hans -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
