Computer implemented method for automatically managing stored checkpoint data

摘要

Computer-implemented methods and computer systems for automatically managing stored checkpoint data are described. The method includes accessing a first user defined time period. The first user defined time period is related to a plurality of stored checkpoint data, and each checkpoint data of the plurality of stored checkpoint data has an associated storage time. Further, the method includes identifying a first set of checkpoint data having storage times that are within the first user defined time period. Moreover, the method includes identifying a second set of checkpoint data having storage times that are older than the first user defined time period. In addition, the method includes pruning the second set of checkpoint data according to a user specified process in proportion to storage time of each checkpoint data of the second set of checkpoint data. The older stored checkpoint data is more heavily pruned over recent stored checkpoint data.

1. A computer-implemented method of managing stored database checkpoint data, said method comprising:
accessing a first user defined time period, wherein said first user defined time period is related to ages of a plurality of stored database checkpoint data, and wherein each database checkpoint data of said plurality of stored database checkpoint data has an associated storage time; identifying a first set of database checkpoint data having storage times that are within said first user defined time period; identifying a second set of database checkpoint data having storage times that are older than said first user defined time period; and automatically pruning said second set of database checkpoint data according to a user specified process in proportion to storage time of each database checkpoint data of said second set of database checkpoint data, wherein older stored database checkpoint data is more heavily pruned over recently stored database checkpoint data.
