I have run out of disk space on my server.
It is running Ubuntu 10.04 LTS and hosting a handful of applications and their associated MySQL databases;
I currently have 2x 160GB hard disks. One is used by the OS and the other is used to backup the application data daily. This eventually get backed up to an external location.
The majority of the disk is being used by the application data which is located in a home directory.
I'm thinking of buying couple 500GB or 1TB drives.
I'm unsure whether i should leave the OS on the 160GB and mount the home directory on the new hard disk, using the second new disk as a backup.
The other option is to clone the two existing drives onto the new drives and continue as is.
