Disk-based archiving is really the key to being able to store data directly on the archive, bypassing the migration process. Active data isn’t growing very quickly at all, some studies show less than 5% of active data is growing. Disk archives present their archive storage via a network mount point (CIFS or NFS) and as a result show up as just another drive on the network. With that a user, once given access, can store. data directly to the. archive, saving primary storage space immediately.”]
