Abstract: Systems and methods for asynchronous backup of virtual disks in a distributed storage array are disclosed. An exemplary method may comprise receiving an IO stream at the virtual disks in the distributed storage array, writing data to one or more storage cells of the virtual disks in the distributed storage array, and logging completed writes in a first batch for each of the one or more storage cells. The method also comprises establishing a consistency point in the IO stream, terminating logging to the first batch for each of the one or more storage cells at the consistency point and logging completed writes after the consistency point to a new batch for each of the one or more storage cells. The method also comprises transferring writes logged in the first batch to at least one remote storage so that the at least one remote storage is crash consistent.

Distributed back up of data on a network
Robert Thomas Cato,Eugene Michael Maximilien +1 more
- 16 Mar 2000
Abstract: Within a network of computers, a system administrator function controls the backing up of data of client machines to selected other client machines within the network by removing control of and access to portions of the hard files within those machines to the local user. The freed up storage space within the client's local hard files is then used for backup purposes to backup data from other machines within the network. Agents in the server and client machines perform this task making it possible to distribute the backup workload across the network. There are three modes of backup: source initiated, target initiated, and server communal backup (CB) agent initiated. All are coordinated by the server CB agent.
