![]() In addition, the LTO backup software will be able to send the necessary commands to the tape library to have the required tape moved into the tape drive as required.Īs one tape fills up, it can be replaced with another from the pool. When we wish to perform a backup, the target storage is addressed via the pool, rather than individual tapes. When using tape libraries, barcodes are attached to the spines of tapes to allow automated identification. The allocating of tapes requires that they are physically available to be written and identified. LTO Backup software will allow the creation of these pools and allocation of individual tapes into them to add capacity. Add 9 more tapes and our 10-tape pool now has 120TB of backup capacity. A pool with one LTO-8 tape will have a capacity of 12TB. Rather one is interested in some grouping of several commonly called a ‘storage pool’ or ‘storage set’.ĭifferent software vendors will use different terms for the same concept, we will use ‘pool’ here. When configuring backup software, one is not generally concerned with individual tapes. ![]() ![]() Tape libraries have robotic mechanisms that move tapes, as controlled by the LTO backup software. The former requires the manual insertion of tapes, the latter comprise many tapes and LTO drive(s) in a unit. Broadly, LTO tape hardware falls into two categories, standalone (or tabletop) LTO drives or LTO libraries (or jukeboxes/autoloaders). ![]()
