I would like to feedback on this:
I am assuming you are refering to classif file archiving agent.
this wil work only if the files older than 5 years and files between 3 and 5 years are in the different folder. if the are all mixed in the same folder then this will not work, as the file archiving subclient does not allow 2 subclient with same path.
If the files are all mixed in 1 folder, I think the alternative is to do this:
-create a file archiving subclient for the folder and attach to a storage policy with primary copy to disk and secondary copy to tape.
- first set the rule to archive files more than 5 years old, run the archive job and then make sure all data is auxed to tape.
- delete the archive job on the disk copy.
- then set the rul to archive files more than 3 years oold, and schedule the archive job moving forward.
