raid 1, raid 0 and off site backup
hi,i am thinking using raid 0 (2x80gb ide drive, or 2x36 gb scsi drive), rather conventional raid 1, for my colocated server.
Raid 0 is very risky, but with the benefits of speed and cheap, as compared with Raid 1. Most people use raid 1, do not use raid 0. And also do offsite back up.
I intent to rely on my home computer to do daily backup only.
I think offsite backup has advantage and disadvantage vs. Raid 1. But in the end, the advantage is over disadvantage, if my file/websites is not so critical.
advantage of offsite backup: very safe, can against corrupted data, easy to use, easy to set up. can against many other disasters that Raid 1 can not (fire, etc. )
disadvantage:
the only major advantage of Raid 1 compare to offsite backup is, you May recover and be back online several hours earlier as compare to offsite backup, when there is a hard disk failure. But hard disk failure is very rare.
Loss one day's data is not really my big concern.
How do you think?
thanks
