Using Ubuntu as a backup server

1. Install Ubuntu 8.04 LTS with a minimal install
2. Use apt-get update to update the repositories
3. Use apt-get upgrade to make your new server current with security patches
4. Use apt-get install rsnapshot, rsnapshot will be the backup technique we will use
5. Configure your raid volume where your backups will be stored
6. I use a hardware raid card, so all I need to do is make the partition.
7. Use fdisk to create the partition.
   fdisk /dev/sdb
8. I use jfs for my backup storage filesystem
9. Use mkfs.jfs –L raid5 /dev/sdb1
10. Add the new partition to /etc/fstab
    LABEL=raid5     /mnt/raid5      jfs     rw,atime        0    0
    If you want you can use blkid to get the UUID of the new partition and use UUID instead of LABEL in /etc/fstab
11. If you try to mount the partition, you will probably get an error relating to there is not a /dev/ created yet.
12. You now need to run partprobe to create the new /dev
13. Now you can mount the partition
14. mount /mnt/raid5
15. Now we can edit the rsnapshot file located at /etc/rsnapshot.conf
16. Set snapshot_root to be on your newly created partition like below
    snapshot_root   /mnt/raid5/rsnapshot/
17. Skim thru the rest of /etc/rsnapshot.conf and modify as needed.
18. Update here about ssh-keygen –t rsa
19. Update here about sftp id_pub to server 2
20. Update here about server 2 path in /etc/rsnapshot.conf
21. Update here about running rsnapshot daily
22. Update here about adding cron entries
23. Update here about adding a samba share to access the backup from windows.
