Business needs
Businesses today want fast, reliable storage solutions, which are easy to manage, along with
comprehensive technologies for data recovery. When disasters hit, the true test of your abilities is the
speed by which you get data back online.
What problem is this solution meant to solve: Two Stage Backup utilizing the MSA1500 and tape
storage is being released to address customers’ shrinking backup windows. Using SATA disk
technology allows for higher capacity at a lower price and offline backup and restore. This solution
increases overall system performance by adding high-speed targets to the backup environment.
Adding a mezzanine approach to conventional tape-only backup offers many advantages during the
backup and restore processes, including:
•
Improved reliability using low-cost disk storage with RAID-based data protection
•
Improved data availability with faster single file restores
•
Improved backup system scalability using up to 24 TB of near online storage capacity
•
Improved backup and recovery system performance that can reduce the overall backup and restore
window required
