A method for backing up data in a computer system from at least one primary data source to a secondary data source is provided. The method includes performing a full image backup on a plurality of data blocks stored by the primary data source(s). An incremental backup can then be initiated at a predetermined interval. During this incremental backup, the modification time of each file/folder at the predetermined interval can be compared to a defined time. If the modification time is earlier than the defined time, then the data blocks of that file/folder can be excluded from the incremental backup. If the modification time is later than the defined time, then the data blocks of that file/folder can be included in the incremental backup. This method can be used to provide an efficient disaster recovery using a network.

Method and system for providing image incremental and disaster recovery

The data from a plurality of primary data sources, such as disk drives or disk arrays, are interleaved and captured in a secondary data source, such as a tape drive, during a backup operation. The interleaving of data allows the overlap of read/write operations performed by the plurality of primary data sources, thereby optimizing the performance of the backup as well as the restore.

Method and system for providing an interleaved backup

A method for backing up data in a computer system from a plurality of primary data sources to a secondary data source is provided. The method comprises copying data sections from the plurality of primary data sources to the secondary data source and providing a data pointer on the secondary data source. The data pointer indicates a starting point of each transfer from the plurality of primary data sources and where that starting point is on the secondary data source. This data pointer information provides the minimum information necessary to map a location from the primary data source(s) to its location on the secondary data source.
