Features |
The need
for robust, fast, high-capacity backup
designed for mission-critical data has
never been stronger. With the advent of
the M490L Autolibrary, you can now have
easy, automatic access to 15 standard
1/2 inch data cartridges, providing all
the benefits of true mainframe-class backup
and hierarchical data storage management
(HSM) at entry-level prices and in desktop
space.
Utilizing twin 7-cartridge magazines,
the M490L allows operators to easily handle
many cartridges at once. The 15th slot
can be used for "priority" jobs
or a cleaning cartridge.
The M490L currently houses one M490E cartridge
unit, and coming in 1996 is a two drive
version, ideal for Disaster Recovery planning
where dual backup sets can be created
simultaneously, one for offsite safekeeping
and the second for on-site file recovery.
