Q: What is the ATTO FastStream Virtual Tape Appliance?
A:

The ATTO FastStream VT is a virtual tape appliance that sits in front of disk storage. It is not bundled with storage for flexibility. The appliance can be seamlessly integrated into an existing backup environment.  The FastStream can be set up in a variety of configurations. Two virtual libraries can be created with up to 30 Virtual Tape drives and 256 Virtual Tapes per library.The ATTO FastStream VT offers industry leading performance and the enterprise-class reliability of Fibre Channel and SCSI technologies.  This technology allows the FastStream VT to utilize a Storage Area Network (SAN) to perform up to 60 concurrent backups per virtual tape library.   The ATTO FastStream VT is a unique solution that leverages ATTO’s engineering expertise in data management.  The FastStream VT offers high-performance features such as hardware-based RAID, high-availability components and a fault tolerant, field serviceable design, all in a standard 1U – 19” form factor.

Q: What is virtual tape?
A: Virtual tape appears and functions like a traditional tape drive or tape library.  It appears to the ISV application as though it were a tape-based product. A benefit of virtual tape is increased performance given that the underlying technology is disk based. Disk is generally 2 to 15 times faster than tape which then can significantly improve backup and restore times. Virtual tape can be used anywhere traditional tape is used.

Q: Is the FastStreamVT suitable for enterprise-class backup applications?
A:

The FastStream VT is optimized for Mid-tier Enterprise backup needs. The FastStream VT supports a wide selection of backup solutions and configurations.  The FastStream VT offers four key aspects to supporting an Enterprise’s backup needs:

  1. Capacity  – On-the-fly tape expansion

Q: Is a separate license needed for FastStream VT in addition to existing tape drives and libraries?
A:

There are no additional charges for licensing the FastStream Virtual Tape hardware, however your backup software may require specific licensing for virtual tape drives or capacity  If you are licensed by single devices it will require an additional license unless you are replacing your existing library with the FastStream.

Q: How difficult is to set up the FastStream VT?
A: Thanks to the one-click design of the FastStream VT, setup of a virtual tape library has never been easier.  Our setup wizard is accessed via a browser-based GUI and provides a quick and complete setup of the FastStream Virtual Tape appliance.

Q: How quickly can I restore a file with virtual tape?
A:

The FastStream VT writes tape data to disk drives.  By using random access disk drives instead of sequential access tape drives, restores of files are almost instant.  If a small file you are looking for is at the end of a 500GB tape, with physical tape you have to wait a while to restore that file.  With virtual tape, the FastStream simply goes to the location of the file, and restores it to your system.

Q: What are the advantages of the FastStream VT appliance relative to disk-to-disk backup?
