Now add a half descent user interface and you'll have a good product.

That, and . . . #

. . . perhaps EMC can make the whole product less of a bug-ridden pile of colon meat. Adding new features is well and good, but they may want to look at making the existing ones function reliably.

Networker still exists? #

By Anonymous Coward Posted Monday 15th October 2007 22:33 GMT

The only reason Networker still exists is because EMC bought Legato and they are bundling this with SAN sales. This company should have been taken to the woodshed and mercy killed several years back for the good of the whole IT community.

CommVault is so far ahead of the game here, Netbackup a close second. Tivoli is expensive/clumsy and Data Protector is proprietary - not qualified with much outside of HP gear.

IBM TSM does CDP, etc. #

Contrary to the article Tivoli Storage Manager does do CDP today.

Also Data De-duplication is supported at the hardware level on IBM's N-Series storage controllers (which work fine as TSM disk pools) and is in the roadmap for a software-only solution.

And with TSM's incremental-forever design there is much less duplication than other backup products to start with.

...will support 1TB SATA ... and also offers RAID6 #

By Alan Parsons Posted Tuesday 16th October 2007 14:19 GMT

Well it would have to, wouldn't it? Essentially RAID6 offers protection against double disk failure, and given the MTBF of even 1/2 Tb SATA drives there's no way I'd commit my data to it - even backup data - without at least RAID6 in place.. High density SATA drives seem to be assembled in factories whose idea of a clean room is sprinkling some water on the floor to keep the dust down.
