we copied by rsync a volume containing MANY MANY files (28,819,704) from an old EMC Celerra array to a Netapp FA8060.
On source, I have about 2 TB of data that, with deduplication on, become 1.4 TB.
On destination, I'm already at 1.9 TB and rsync still doesnt' end, in spite of deduplication and compression saving of about same percentual of EMC.
How is it possible? Is there some basic difference of block size?
