Shadow Copies - Disadvantages? What are they?
Posted on 2004-11-10
I am going to setup shadow copies and was thinking of creating a shadowed copy at 11.am , 1pm , 3pm, and 5.30pm.
We have an HP Proliant M series. it has a 3ghz Pentium 4, 512mb ram, and 3 250gb sata drives running in raid 5 giving us 500gb storage.
Would this amount of shadow copying slow down the server by a significant ammount? Or how much would it slow down by? And would it be advisable to shadow copy every 1 hour, or perhaps every 2 hours? Staff are generally using computers from 8am - 6pm.
