I have a file server with a secondary raid 5 array with a total capacity of 408GB with 389gigs being used. I really need to swap in a set of 400gb drives replacing the existing 147gb's.
However I do not have another network location with enough free space to temporarily house this data plus I really need to keep the current folder level security settings.
I'm of the opinion that my only solution is to do a standard backup/restore using Symantec Backup Exec to a local LTO3 tape drive. However my worry is that the downtime window is going to exceed 12 hours.
I'm looking for opinions here on any possible faster ways of handling this task.
