I only spent 6 hours writing those posts, no biggy. I really enjoyed doing it so it wasn't a hassle to me. That was my work. I've been wanting to tell somebody about how I setup BackupPC so this was great. I still to talk more about the host interfaces and some more specific topics of interest but I purposefully left them for another time.
The LDAP one is the one I'm hoping for the most since I haven't, and probably won't, create BackupPC users until 2 things are fulfilled, LDAP users sync'd with eBox users and HTTPS connections. Right now, it's only HTTP so I don't want access to it from the outside at all.
I've been shrinking my 1.2TB ext3 to a 160GB on a hardware RAID3 using Gparted on the Linux Mint 8 Live. It's been taking quite a bit of time; resize2fs has been running for 29 hours now. I feel like I should've made the partition larger to fit the 465GiB partition I'm moving it to, but I didn't do that because I wanted the dd to move faster. Well... Bad idea I guess.
I've already setup a RAID1 and RAID5 using mdadm and the SATA ports on the motherboard to prepare for the move. I'm moving to 3x250GB drive. I setup a 131MiB ext2 partition for /boot in RAID1 mode with all 3 drives and the rest is for / in RAID5. Had to do that or I couldn't boot to the RAID5. Just waiting for this resize2fs operation in Gparted to finish so I can dd the data. I thought I'd easily need some 300-400GB for BackupPC, but how I have it configured, I don't need that much at all. Now say I backup a lot of data I have in my RAID setups, sure, I could fill that sucker up but I'm not doing that for the reason that I don't have the space requirements or the finances to have the space requirements to do so since it'd easily require at least 2TB of storage capacity, maybe more. Don't forget the amount of bandwidth and computational resources and heat/power from backing up 1TB+ of data in a full backup. It still would have to look for modifications to files in those files as well adding a ton of disk reads adding network traffic and more heat/power.
BackupPC is a major player in the backup arena, but I don't think there's any solution for this massive of a data-set unless I have two pools or large enough drives. I really don't /need/ to backup terrabytes of data, but it would be nice yes. That's actually not a bad idea if I could get a hold of some more 640GB drives or some TB+ ones in the future. Keep that in mind, no backup solution is going to be really good at backing up many terrabytes of data unless you have a SAN and some fiber links.
I don't have time (motivation) to write a HowTo. If someone else wants to, I can give them all the info necessary that they'd probably ever need. Best to ask me sooner than later because I tend to forget stuff pretty quick that I don't use daily and then I'll remember everything as it comes back which is terribly out of order.
