Hi. I'm trying to backup a large storage server with 3.2 TB worth of storage space. 900 GB is currently being used. We are doing offsite backups through a 100 MB fiber connection and backing up to a 9 TB Dell Power Vault. I just tried making a full backup and it took over 3 days to complete. Is this normal for this amount of data? Why else would it take so long? Also, I would like to perform incremental backups after my full backup. How long should I keep performing incremental backups between full backups? 30 days? 15 days? Every six months? Thanks!
