ARKEIA

Arkeia supports incremental as well as complete backups, which can be scheduled. Its unique transaction engine allows multiple backups & restores to be performed simultaneously. This is especially valuable for multiple users backing up or restoring data on their own. (A multiple drive library is required).

Arkeia 4.2 offers 3 interfaces: a terminal interface, a X-11 Motif GUI, a terminal interface & a Java interface, which enables the system administrator to manage multiple remote backup servers through Internet as if they were local backups. Operators can use any Intranet station to access any remote network. Its universal interface allows users to backup via the Internet.

Networking
Arkeia has its own network protocol that runs over the top of TCP/IP. This protocol allows a client to be physically disconnected for a considerable time during a backup. The protocol will recover the backup from the point of interruption when the connection resumed.
Arkeia is able to use up to 80% of the network bandwidth. To prevent the network from being overloaded the "Cruise Control" facility allows the administrator to dynamically limit the bandwidth available during a backup, or to preset the bandwidth limit in the savepack.

Performance
Clients are backed up in parallel with the data being multiplexed onto the tape device(s). Up to 200 clients can be processed concurrently to 32 tape devices. Flows of data are automatically optimised from each client, so that no client can slow the overall backup speed. The multiplexing technique used will allocate bandwidth depending on the rate that each client is supplying data.
