Backup ... Raid 0 ... Raid 1
Getting my first server soon and going to co-lo it ... but need some advice on the appropriate backups to run ...
Server - RH7.2 with Ensim
Will purchase 3 HDD and was thinking of running them as follows :-
HDD (A) 80GB Main Drive - install RH 7.2 with Ensim and all the patches and use this as the main drive
HDD (B) 80GB Secondary Drive - install onto the server as a secondary drive and carry out a nightly mirror of the Main drive, what commands or scripts can I use here ? Rsync ? MirrorDir ? Or would you suggest an online Raid 1 mirror ? How can I achieve that when there isn't a hardware Raid card installed .... ?
HDD (C) 80GB Additional Drive - will be kept offsite in my office on another spare PC connected to the internet via a 512K DSL line. I will need to get an exact replica of HDD(A) on a nightly basis via a cron job. any suggestions here ? Rsync ? Mirrordir ?
Oh.. when I mean exact replica .. I mean everything from OS to config files to user data to mysql etc ...
Bandwidth in and out of the server isn't a problem - have lots of it.
Would appreciate any help rendered. Thank you.
PS - would you consider this kind of backup / RAID relatively okay for a simple web and email server ?
