In a nutshell...

16Tb of total storage on a SAN. We currently use 7Tb of the SAN. We have 33 virtual servers and around 5 physical servers running SQL and Exchange. Backup window is Friday 5pm till Monday 6am. Current backup device is a Dell Tape Library with 2 x LTO3 tape drives.

I am looking at changing and updating the whole backup system so that we can try and have full 24/7 access for staff at home, so as little interruption as possible would be very useful. Do I stick with tape, go to disc ??

Any advice is very much appreciated.

What's your budget? –  Chopper3 Nov 11 '10 at 10:25
can you give some more information about your SAN? SAN is synonymous with cloud , they can have lots of meanings. –  The Unix Janitor Nov 11 '10 at 11:06
The SAN is an Equalogic PS5000 –  Scott Jackson Nov 11 '10 at 11:17
Is the speed of backup (and recovery) important or not? –  Cry Havok Nov 11 '10 at 12:11
Your requirements aren't clear - what is it you're trying to achieve? Are you saying that your current solution doesn't back up all the data in the window you have? Are you unable to meet your Recovery Time Objective with your current setup? 24/7 access for staff from home isn't a backup requirement and should be fairly trivial. Perhaps you are enquiring as to whether staging your backups to disk then to tape would bring you benefits? i.e - you'd have access to recent backups on on-line storage (a disk array) and archive older backups to near-line storage (tape). –  Rowley Mar 30 '11 at 11:35
