seriously, get a 3ware controller; you'll never want a box without one again. even a 2-port one is $130 well-spent, even on a home machine. though it sounds like advertising, Carl is perfectly right...

Re: [BackupPC-users] some questions...
I've had particularly good results from the 3ware 9500 series 4port controllers. They run about $325 US dollars. I work with a company that archives massive amouts of video data, and before a client is ready for the 15 SATA NAS, you can get spectacular results out of a 4 port with PCI interface. They do have PCI(X) as well if speed is an issue. I have built at least 10 boxes with these guys running a raid 5 array, and the 3 drive failures I have seen were always handled beautifully by the controller, and rebuilt without any problem. And no, I am not an employee or partner of 3ware!

Linux RAID1 mirrors work nicely too, and can actually mirror over more than two drives. I use 2 internal 250 gig drives and once a week add a matching external firewire drive and let it sync, which takes a couple of hours, then swap it offsite. I keep a laptop with backuppc installed for quick access to the external drive. There might be a better way to do this with LVM now but this approach should work up to the 750 gig drives that are available now. -- Les Mikesell [EMAIL PROTECTED] - Take Surveys. Earn Cash.

I agree that 3ware controllers are good hardware and worth the money, but I suspect you are comparing the time of swapping an internal drive vs. a swappable cage here. It's not that hard to type an fdisk command followed by an mdadm --add command. Many/most IDE controllers do lock up when one of the drives fails with certain failure modes - this can be a problem especially if your boot drive is there. Scsi tends to fail more gracefully. -- Les Mikesell [EMAIL PROTECTED] - Take Surveys. Earn Cash.

At least, that's my real-world experience with the process. it's noteworthy that I'm in a consulting environment, rather than being a full-time admin for one company. so going off to do something else productive while the drives are sync'ing, or a long command is running, is not always an option. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com - Take Surveys.

For a permanent replacement, there is no need to wait for anything. we consider it good policy to wait for the drives to sync, and do a test reboot, before leaving the customer premises. the reboot is important, as it often shows up problems you didn't notice, or put off until 'after this next command'. You can use the machine normally while the sync happens and it takes care of itself when finished. yep. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com - Take Surveys.

Booting from software raid is a special case in that it really just uses one member so there are some quirks about getting the boot loader installed on both drives and configured to match the bios concept of which drive it is. My approach here is to not worry about it as a special case but keep a boot/install CD around to fix things after the fact like you would any other problem that requires a re-install of grub. The tradeoff is that the drives can be moved to any PC with standard controller or stuck in an external USB/firewire case. I haven't tried that with a disk pulled out of a 3ware set but I'd be surprised if it works. In any case, I like to have the backuppc archive on its own separate partition and it usually takes the whole disk so booting from raid is really a different issue. -- Les Mikesell [EMAIL PROTECTED] - Take Surveys.

You also need to set a partition as active and reinstall LILO, and rewrite the boot sector of the new drive. Doing this ensures both drives are bootable. - Take Surveys. Earn Cash.

[BackupPC-users] some questions...
Hi. Using Backuppc (debian) successfully in my company for about 5 months, backing up 6 winXX shares using samba. The machine is a simple Pentium 4 with a 40GB HD that is getting full. Already ordered a 250GB ata100 hd. but I'm not sure what to do... should I use the 250Gb for the data only, or just replace the hd's using ghost?! Other thing that I didnt know how to do is to make a backup to record to DVD. Most of the hosts are backed up 2 times a day, and it has xfermethod=smb, I can't put in here archive, right? how can I archive a backup to dvd?! cause I will need to make permanent backups to archive to DVD in the end of the year... btw, is it possible to backup thought ftp?, or mount an ftp ?!, it is a local machine, IBM AIX that does not have NFS installed and I don't want to mess in there... and the email summary... I am trying to configure exim4 to sendmail by a smarthost but it is getting tricky... sometimes sends email other don't.. but these emails I send are with manual command mail or sendmail ... I didn't get how I can configure backuppc to email-me if a backup fails... I hope you understand my bad english :) Thanks a LOT! - Take Surveys. Earn Cash.
