Our situation:
We are running BE 2010 on Win 2003 server. We have LT05 and LT04 tape drives.
We have a file server that contains approximately 900gbs of data, for which we do weekly full backups and daily incremental backups. The incremental backup size averages between 2 and 4gb of data per backup. Due to the size of the full backup I am having to change tapes more freqently. I am considering going to a monthly Full backup and daily differential backup scheme. Since differential backups are cummulative, would my final differential backup of the month be between 40 and 80 gbs (assuming 20 differentials between full backups)?
From what I have read, it seems like a combination of monthly full backup and daily differential backups is a good combination from a restore point of view.
I welcome and solicit your comments. I guess my ultimate goal in changing the backup scheme is to reduce the number of tapes I am using throughout the month. I have read the blog from PKH on the Pros and Cons of Various Backup Schemes.
thanks,
Linda
