File Vault Store Partition - RAID Failure

Hello

We had a RAID failure a few days ago.

Our file vault partition was on this RAID and the data is unrecoverable.

However we have managed to restore a recent back up of this partition from a back up dated 241015.

My concern is that the files that have been identified to be backed up since the back up will get missed.

I have 3 file system archive tasks scheduled to run daily. according to EVENT ID 40987, the last time they ran (01115) they identified circa 27500 files.

Our policy is for the files to change to shortcut after successful completion of a back up ( we use Back Exec)

Can somebody advise 

Thanks

Lois
