Abstract
A serverless backup system for backing up information on a network including one or more servers, includes a backup storage system for backing up information and a storage system for storing information to be backed up and restored, wherein information being backed up is transferred directly from the storage system to the backup storage system without going through a server and information being restored is transferred directly from the backup storage system to the storage system without going through the server.
Claims27
A serverless backup system for backing up information on a network including one or more servers, comprising:
- a storage system for storing information to be backed up and restored, the storage system operable to:
- receive the information from a plurality of workstations;
- and
- store the information received from the plurality of workstations;
- and
- a backup storage system for backing up the information and restoring the information, the backup storage system coupled to the storage system and to one or more servers via a network, the backup storage system operable to:
- obtain a static view of a relevant portion of the storage system, wherein the static view is obtained using one or more of a backup mirror system and taking a snapshot of the relevant portion of the storage system, wherein a period of write inactivity to the storage system is waited for prior to obtaining the static view;
- map one or more blocks of data comprising the information being backed up to corresponding files;
- and
- back up the information by transferring the information being backed up using one or more data movers operable to transfer the information being backed up directly from the storage system to the backup storage system, using one or more extended copy commands, without going through the one or more servers;
- and
- restore the information by transferring the information being restored using one or more data movers operable to transfer the information being restored directly from the backup storage system to the storage system, using one or more extended copy commands, without going through the one or more servers.
A serverless backup method for backing up information on a network including one or more servers, comprising:
- providing a storage system for storing information to be backed up and restored, the storage system operable to:
- receive the information from a plurality of workstations;
- and
- store the information received from the plurality of workstations;
- providing a backup storage system for backing up the information and restoring the information, the backup storage system coupled to the storage system and to one or more servers via a network;
- obtaining a static view of a relevant portion of the storage system, wherein the static view is obtained using one or more of a backup mirror system and taking a snapshot of the relevant portion of the storage system, wherein a period of write inactivity to the storage system is waited for prior to obtaining the static view;
- mapping one or more blocks of data comprising the information being backed up to corresponding files;
- backing up the information by transferring the information being backed up using one or more data movers operable to transfer the information being backed up directly from the storage system to the backup storage system, using one or more extended copy commands, without going through the one or more servers;
- and
- restoring information by transferring information being restored using one or more data movers operable to transfer the information being restored directly from the backup storage system to the storage system, using one or more extended copy commands, without going through the one or more servers.
A computer readable medium including code for performing a serverless backup method for backing up information on a network, the network including a storage device for storing information to be backed up and restored, the storage system operable to receive the information from a plurality of workstations and store the information received from the plurality of workstations, the network further including a backup storage system for backing up the information and restoring the information, the backup storage system coupled to the storage system and to one or more servers via the network, the code comprising:
- code for obtaining a static view of a relevant portion of the storage system, wherein the static view is obtained using one or more of a backup mirror system and taking a snapshot of the relevant portion of the storage system, wherein a period of write inactivity to the storage system is waited for prior to obtaining the static view;
- code for mapping one or more blocks of data comprising the information being backed up to corresponding files;
- code for backing up the information by transferring the information being backed up using one or more data movers operable to transfer the information being backed up directly from the storage system to the backup storage system, using one or more extended copy commands, without going through the one or more servers;
- and
- code for restoring the information by transferring the information being restored using one or more data movers operable to transfer the information being restored directly from the backup storage system to the storage system, using one or more extended copy commands, without going through the one or more servers.
