Hi Paul It would be helpful to know what kind of the tape technology you're using since the reclamation threshold % is usually based off which technology is being used. Smaller tapes can usually have a small threshold while larger tapes requires a larger threshold.
One way to reduce the amount of tapes is simply to reduce the threshold to something like 30 and let the reclaim process run until it's complete. This will require enough free tape drives to a) let reclamation run until it's complete b) do normal operations. There can be several reasons why you get so high pct reclaim. One is that you're running full database or application backups. Since this will expire a full backup every day, it will cause the reclaim on your tapes to rise. Splitting your copypool into separate ones categorized on the type of data stored (one for fileservers, one for application servers for example) is one way to go, using collocation is another.

Expiration runs daily and I run reclaimation daily on this copypool, set to 50. Is there anything I can do to try and consolidate the data onto fewer copypool tapes?
