Hi,

some questions according deduplication:

1.) when a client backups deduped to a small, but fast filepool (for daily amount), and the rest resides in the successor pool, is it deduped all over the machine, or just for that small pool?

2.) when migrating from one Filepool to the other (both dedup), is the data inflated? Moreover, if already "identified" duplicates in that pool, are those migrated, or jumped above?

3.) Implied Qestions: Does Deduplication happen only within a pool, or across all Filepools?

The reason why not having just one pool is, that the second one could be on "cheaper" disk, which are maybe not "mirrored SAN".

Best Regards,
Alexander Heindl
