Automated backups, full disk image
I have a server running ubuntu 10.04. It would be an awful thing if i ever lost the disk. I do file backups across the network. What i would like to do is create an image of the disk (probably weekly), i could put another drive in which will be the image of the current system disk.
From doing research i know a lot of people will boot to a live cd and then use dd. Can anyone help me out in automating the process? Manually doing this every Sunday isn't something i would like to have to do. thanks Joe |

I take what i was given. This is for work. Although i may look into something like that, but i think the company has a plan to upgrade our VM server, so when that happens i can just have them take snapshots.
For now i think this option would be best. |

Think about what you're backing up, do you really NEED a disk image? Would taking a full file-system backup to tarball on a remote machine or a physical tape along with a properly documented restore procedure mitigate the risk enough? I've implemented a similar strategy several times along with six-monthly DR testing and it's worked out fine. |
I'm looking for the easiest solution, if it is possible to make automated disk images to a drive thats already in the machine, that would work out best, because if the drive dies, you reboot from the other drive. Very little downtime.
if i were to copy all the files to the other drive, if the first drive dies, i would have to install the bootloader on the other drive correct? Or is there a way that i can prep the drive, so its ready to go, so all i would have to do is boot from the second drive because all of the files were recent? I've never had to do any recovery regarding the boot loader, so i would need some help as to what i can do in that respect. thanks Joe |

make a clone/image to the second drive, so that if you test run boot from it, it starts 2.nd: make rsync or whatever backup from 1.st drive online to 2.nd drive, so the changes are archived as many times /day you want or need to do it. Anyway, a RAID1 is what you want and is rather cheap for a company playing with loosing data (around $100 max. for a HW RAID card) good luck |
