Abstract
There is disclosed apparatus and processes which address problems in the area of providing high availability and disaster recovery for computing systems and the data in them. These apparatus and processes can be used to provide high availability and disaster recovery for a computing system to be protected. The protected computing systems may be virtual computing systems.
Claims7
A process for creating periodic backups of a protected system P comprising:
- a cyclical replication process comprising, in sequence:
- creating a consistent point-in-time snapshot of a protected system at a time t,
- creating a content manifest of the snapshot Mt(P),
- generating a delta manifest Dtt−1(P) comprising a set of information needed to transition between Mt(P) and Mt−1(P), wherein the set of information is sufficient to enable deriving Mt−1(P) from Mt(P), and
- transmitting the delta manifest Dtt−1(P) to a repository.

Apparatus for creating periodic backups of a protected system P, the apparatus comprising:
- a processor
- a memory
- wherein the processor and the memory comprise circuits and software for performing a cyclical replication process comprising, in sequence:
- creating a consistent point-in-time snapshot of a protected system at a time t,
- creating a content manifest of the snapshot Mt(P),
- generating a delta manifest Dtt−1(P) comprising a set of information needed to transition between Mt(P) and Mt−1(P), wherein the set of information is sufficient to enable deriving Mt−1(P) from Mt(P), and
- transmitting the delta manifest Dtt−1(P) to a repository.
