NAS太慢,多数用TAPE,我只管把BAK DUMP到BACKUP SERVER上,网管COPY到TAPE上,一 般都是这么分工的。你的DB需要ARCHIVE了,几个TB都是些什么东西,DATAWAREHOUSE也 没那么大吧。企业版可以COMPRESS BACKUP了,另外可以买THIRD PARTY BACKUP 压缩软 件

check this: virtual tape library . i think it is a EMC solution. then you can get near to line speed when do backup:) after backup is done, use the tape management software to do a tape dupe from Virtual tape to real tape, ship to offsite. Key points: frequency of full backup. Data retention of onsite tape (virtual) and offsite tape. Restore plan? (my previous experience is hosting offsite instances which is smaller by can hold mission critical tables/views so that offsite tape will be restored on top of this machine once arrived, then the DNS entry can be easily modified to pointing to it if there is any major going on)
