As many posts mention when things occasionally go wrong it's goo to have a backup of the data on your ReadyNAS. However we have 55TB of live data across 4 ReadyNAS boxes on 3 separate sites, this data changes daily at about 1TB of changed data per day although that can rise to 9TB on busy days. We do have Symantec Backup Exec with the correct agent so that we can backup the ReadyNAS devices to tape but it's slow and time consuming both for backup and restore and we only have the facility on our main site so not an option for 46TB of data. Does anyone have an recommendations for backing this data up?
backing up 9 TB of data over a 24 hour period over the wide area would require a gigabit of throughput between the sites. So I think you will need same-site backup if these peaks happen very often. Disaster recovery of course means the backups need to be off-site. No simple answer on that one, just pointing out that you probably needed to analyze the WAN data flows as part of the project.
