We currently have around 30 TB soon to increase to 80TB on a full backup which currently goes to tape and is taking far too long. We have a disk based solution which we plan to carry on doing full weekly and daily incrementals using backup exec 2010.
To speed things up i can cut the existing job in to say 5 jobs all going to virtual tape libraries on the quantum.
My question is that after the 1st full backup the next weeks full backup is probably going to have say 80% of its data exactly the same as the previous week. The quantum will dedup this so space isnt an issue but the wasted time it takes to send all that un needed data across the network is.
Has anyone heard of any product or method of backup that can eliminate the sending of the unnecsisarry data.
I like the sound of synthetic backup but have been told that it is only ok if your backups are very reliable for the baseline backup otherwise all your full backups there after will be missing files. we have over 100 servers and never get all of them 100% so synthetic worries me.
