[Networker] in-line dedup datadomain
2011-05-12 11:11:22
I'm trying to figure something out.
Although data from a multiple client backup, is stored in separate files
(according to SSID) on an AFTD device, which means it is effectively
de-multiplexed.
One benefit
of the simple rule that all data in a file belongs to the same save set is that
it enables
clean staging of save sets to another medium.
If a datadomain device is being used (non VTL) mode, is the data stream it
de-duplicates effectively a multiplexed datastream from all the clients backing
up at any moment.
If so how can any decent de-dupe ratio be achieved, as the data stream it's
de-duping is a random mix of each clients data, which will change each time the
backups run.
Thanks
Nick
