Abstract
Various systems and methods for performing incremental backups in transactional file systems. For example, one method involves performing the first stage of a multi-stage write operation, where the write operation writes a data block. The method then involves performing a backup operation. However, the backup operation does not backup the modified block, since not all stages of the multi-stage write operation have been performed. The method involves updating metadata to indicate that though the data block was modified and a backup operation was performed, the data block was not included in the backup operation. After all stages of the multi-stage write operation have completed, e.g., a transaction is committed, a subsequent backup operation is performed. The data block is backed up during the subsequent backup operation.
