A system, method and computer program product for synchronizing data written to tape with improved data recovery. When writing data to tape, an index is kept in memory and updated to reflect change(s) to a file system mounted on tape. After a predetermined amount of data is written to a tape, a device may perform a sync operation, causing the index to be written into a data partition of the tape. If the sync operation is successful, the index in the index partition of the tape can be updated using a copy of the index in the data partition of the tape next time the tape is mounted. If the sync operation is not successful, the device may write the data to a different location on the same or another tape, update the index, and force another sync operation. This process can be repeated.

Systems, methods and computer software utilized in the implementation of tamper protection, where unique information associated with data storage tapes and with particular revisions of these tapes is stored on the storage medium itself and on a memory of the tape cartridge, so that the data can be compared to determine whether unauthorized modifications have been made to the tapes. One embodiment is a system which includes an archive node appliance coupled between a set of hosts and a tape media library. The archive node appliance presents files stored on a tape of a media library as a directory. The archive node appliance maintains tamper prevention data on the tape and on an auxiliary memory on the cartridge of the tape, and determines from this data whether the tape has been altered by an authorized system.
