Abstract
A data center for data backup and replication, including a pool of multiple storage units for storing a journal of I/O write commands issued at respective times, wherein the journal spans a history window of a pre-specified time length, and a journal manager for dynamically allocating more storage units for storing the journal as the journal size increases, and for dynamically releasing storage units as the journal size decreases.
Claims20
A data center for data backup and replication, comprising:
- a server group at a protected site, the server group including a server configured to send one or more input/output (I/O) commands via a network to a disk at the protected site;
- and
- a journal manager at a recovery site, configured to:
- intercept, for a first predetermined window of time, the one or more I/O commands sent via the network;
- select a variable size storage unit from a pool of variable size storage units to store data corresponding to the one or more I/O commands, the variable size storage unit including a variable size data chunk corresponding to a second predetermined window of time;
- and
- store the data corresponding to the one or more I/O commands in the variable size storage unit.
