Definition of Continuous Availability Disaster Recovery
Along with disaster
recovery and rolling disaster, continuous availability disaster
recovery is just another phrase used in regards to backup,
backup program, and backup
recovery. Continuous availability essentially refers to a real
time data replication method. Basically the data is constantly
submitted to a remote site as designated by the user. One
way to create a continuous availability service is to use a
transaction router that will simultaneously route transactions
to both the primary location and its subsidiaries. The transaction
router is a software based tool that performs this task.
Another way is to manually submit through a
FTP drive
over a network. Unless automated, the latter method is of
course tedious and time-consuming.
BackupChain is specialized for Microsoft Windows and capable of providing continuous availability disaster prevention. Its in-file delta compression algorithm is particularly useful for exteren/hyper-v-backup/ for Hyper-V, and VMware.
