Abstract: Archiving a database and point in time recovery of the database. A method includes taking a first snapshot of a database. The first snapshot of the database includes a first snapshot of the data in the data storage and a first snapshot of the log records in the log storage. The method further includes taking a second snapshot of the database. The second snapshot of the database includes a second snapshot of the data in data storage and a second snapshot of the log records. The method further includes restoring the database to a particular point by applying the first snapshot of the data in the data storage to the database, applying the first snapshot of the log records in the log storage to the database and applying a portion of the second snapshot of the log records in the log storage to the database.

Abstract: Data is processed by receiving a list of one or more file system elements in a level of a file system or a portion thereof. The list is sorted based at least in part on whether a file system element is a file or a directory. A sorted list is obtained. The file system elements in the level are backed up according to the order of the sorted list.

Abstract: Traversing hierarchical data is disclosed. A first list of items in a first level of the data is received and sorted in an order. The data of the first level is processed in the order of the sorted first list. If any other level of data is encountered during processing, another list of items in the encountered level is received and sorted in an order. The data is processed in the order of the list.

Abstract: Resuming processing of a hierarchical data is disclosed. A previously-processed part of the hierarchical data is traversed by starting at a first level of the hierarchical data, omitting at least one processing operation with respect to data in the previously-processed part. Sub-levels, if any, are descended only if they lead to a restart location within the hierarchical data. Normal processing is resumed starting from a next data after the restart location.

Abstract: Locating data last saved during backup is disclosed. A segment ending offset relative to a reference point of a last segment of data associated with a hierarchical data set is determined. The last segment is the last data associated with the hierarchical data set to be saved on a storage media. A location within the hierarchical data set of a data object that was the last data object saved completely to the storage media by comparing a data object ending offset relative to the reference point with the segment ending offset is determined.

The data of the first level is processed in the order of the sorted first list. If any other level of data is encountered during processing, another list of items in the encountered level is received and sorted in an order. The data is processed in the order of the list.
