Storage specialist Exabyte has launched two mirroring products designed to produce multiple copies of back-up data in the same time it takes to make a single copy.
The Exabyte M10 is a standalone mirroring controller, with one SCSI interface in and two out, which connects a host to two Mammoth tape drives. This product is for companies which already have Exabyte's Mammoth tape drive.
The M10 allows two backups to be created simultaneously at two separate sites, connected via a fibre channel bridge, for security and disaster protection.
The Exabyte M12 includes two Mammoth tape drives for companies without a backup product.
"It could be argued that having multiple backup copies is a bit extreme, but for financial companies, billing operations and large companies, it is critical," explained Steve Georgis, marketing director at Exabyte.
"Firms are taking risks when backing up their data because of the huge amount of time it takes to create multiple copies," he continued. "Currently, in most companies the IT staff have to wait by the system until it completes a copy of that day's data, then replace the tape with a second one to make a second copy. This is crazy when it can be so easily automated."
Pricing for the M10 starts at #2,435 and the M12 at #5,485. Both are shipping at the end of June.
EXABYTE M10 AND M12
The M10 and M12 have three modes of operation:
MIRROR MODE: automatically creates two identical backup tapes for every backup operation, so if one device or tape cartridge fails, the automatic failover option allows processing to continue
INDEPENDENT MODE: allows the tape drives to be addressed independently by the host, just as it would without the controller
COPY MODE: makes a duplicate of the source tape and verifies that the copies are identical.
