Spectra Logic deploys data verification feature

Spectra Logic announced today a new, free software feature across its entire line of tape libraries that will verify that data is stored and can be retrieved by users.

The new feature, called Data Integrity Verification, comes in the latest release of Spectra Logic's library management software, BlueScale 11.3.

Data Integrity Verification works by scanning all new tape cartridges as they're added to a library, ensuring that they are in good working order, are compatible with the system and applications, and are not write-protected.

Once data is written to a tape cartridge, the verification software performs a quick scan of the tape from beginning to end of the first track to ensure that the data can be read. When the cartridge is about to be placed into an archive state -- when it's removed from a tape drive for storage in a library slot -- it's then reverified.

During the reverification process, the library performs a complete checksum verification of all data on tape. It then performs a full read of all data on the tape and makes sure it was written as it should have been and the checksums come out accurately. It follows up the tape archive with notifications every six months recommending additional data integrity scans. It also notifies storage administrators when the data should be migrated off existing tape cartridges to new media.

"Data Integrity Verification dramatically reduces risk, ensures enduring access to archived data and is fast becoming a data center requirement," Molly Rector, vice president of worldwide marketing at Spectra Logic, said in a statement.
