NAS file basis and will run as soon as the cartridge is unloaded and returned to its storage slot
or a NAS file has completed writing and has been closed by the appliance.
L
Library A Library is a Virtual Tape Device that appears to the backup application on the host as a physical
tape library. A tape library is a backup device that has multiple drives and multiple storage slots.
Each storage slot contains a cartridge. This provides considerable storage capacity and full
support for tape rotation strategies. (It may be necessary to upgrade your backup application to
support libraries.)
N
NAS Shares NAS (Network Attached Storage) target devices on an HP StoreOnce Backup System provide
network file share access that is optimized for backup to disk and are referred to as NAS Shares
in the Web Management Interface.
All HP StoreOnce devices that are configured for NAS automatically make use of HP deduplication,
ensuring efficient and cost-effective use of disk space.
It is important to understand that the HP StoreOnce network share is intended to be used ONLY
by backup applications that "back up to disk". Do not use the device as a drag-and-drop general
file store.
NFS Network File System (NFS) is a protocol for interfacing to hosts on a Linux or UNIX network. The
HP StoreOnce Backup System supports this interface for connecting to NAS targets on the HP
StoreOnce appliance from a Linux or UNIX network host.
NTP Network Time Protocol. An Internet protocol used to synchronize the clocks of computers to some
time reference.
R
RAID RAID stands for Redundant Array of Inexpensive (or Independent) Devices, which is a data storage
scheme that divides data among multiple hard drives, increasing data reliability and throughput.
Replication Replication is a standard term used to describe a way of synchronizing data between hardware
in two physical locations. HP StoreOnce Replication allows users to replicate data from cartridges
on one HP StoreOnce Backup System to mapped slots on another HP StoreOnce Backup System
on a remote site or the same system. Once configured (using the simple-to-use wizard), replication
occurs automatically, ensuring data is mirrored from the source to the target HP StoreOnce Backup
Systems. Deduplication ensures that network traffic is minimized.
T
Tape rotation Tape rotation strategies determine when backups are run, the number of cartridges that are
strategies required and how they are reused. Virtual Tape Library targets on an HP StoreOnce Backup
System can easily be incorporated into most tape rotation strategies.
V
Virtual Tape Virtual Tape Devices are backup targets on the HP StoreOnce Backup System to which the backup
Devices application on the hosts write data. They appear to the host as network-attached or locally-attached
physical tape library or autoloader, but physically, they use disk space on the HP StoreOnce
Backup System which, as in tape terminology, is referred to as slots or cartridges.
