Abstract
A backup volume on a backup system is created/updated by reading data stored on a host volume on a host system. A data profile for the host volume is generated based on the read data, where the data profile characterizes the data stored on the host volume. The data profile is sent to the backup system, and data that does not need to be obtained from the host system is determined on the backup system based on the data profile.
Claims25
A method of creating/updating a backup volume based on a host volume, the method comprising:
- reading data stored on the host volume on a host system;
- generating a data profile for the host volume based on the read data,
- wherein the data profile characterizes the data stored on the host volume;
- sending the data profile to a backup system;
- and
- determining on the backup system data that does not need to be obtained from the host system based on the data profile.
A method of creating/updating a backup volume based on a host volume, the method comprising:
- reading data stored on the host volume on a host system;
- generating a data profile for the host volume based on the read data,
- wherein the data profile characterizes the data stored on the host volume;
- and
- sending the data profile to a backup system,
- wherein the data profile is used by the backup system to determine data that needs to be obtained from the host system.
A method of creating/updating a backup volume based on a host volume, the method comprising:
- receiving a data profile from a host system,
- wherein the data profile was generated by the host system based on data stored on the host volume on the host system, and
- wherein the data profile characterizes the data stored on the host volume;
- and
- examining the data profile to determine data that needs to be obtained from the host system.
A system of creating/updating a backup volume based on a host volume, the system comprising:
- a host system having the host volume, wherein the host system is configured to:
- read data stored on the host volume;
- generate a data profile that characterizes the read data;
- and
- a backup system having the backup volume, wherein the data profile is sent by the host system to the backup system, and wherein the backup system is configured to:
- examine the data profile to determine data that needs to be obtained from the host system.
A computer-readable storage medium containing computer executable code to create/update a backup volume on a backup system by instructing a host system to operate as follows:
- reading data stored on a host volume on the host system;
- generating a data profile for the host volume based on the read data,
- wherein the data profile characterizes the data stored on the host volume;
- and
- sending the data profile to the backup system,
- wherein the data profile is used by the backup system to determine data that needs to be obtained from the host system.
A computer-readable storage medium containing computer executable code to create/update a backup volume by instructing a backup system to operate as follows:
- receiving a data profile from a host system,
- wherein the data profile was generated by the host system based on data stored on a host volume on the host system, and
- wherein the data profile characterizes the data stored on the host volume;
- and
- examining the data profile to determine data that needs to be obtained from the host system.
