How to implement snapshots
up snapshots that will likely "age out" of storage in just a few months.
Use heterogeneous snapshot software Many storage systems ship with some type of snapshot software. This may greatly simplify taking or storing snapshots on that particular storage system, but does not guarantee interoperability with other storage systems in your environment. Instead, opt for a...

How to implement disk-to-disk backups
Disk can accept complete backup volumes, as well as simple file copies. For example, backup software can send a full backup volume to a virtual tape library (VTL) emulating the behaviors of a traditional tape system. But disk platforms don't just emulate tape. Files can just as easily be copied to a disk array in the same data center or located on the other side of the...

How to improve tape backup performance and reliability
term storage life.
It may also be necessary to refresh old archival tapes when the tape hardware/software infrastructure changes significantly. For example, moving to a new backup/archive software product or deploying a new tape drive or library platform may render any existing tapes unreadable. In this case, transfer the old tape data to the new tape media. This way you... More... FAQ's
What are the drawbacks of using a virtual tape library (VTL) for data deduplication?
are really no alternatives for disk-based backup outside of backup software options. For example, Symantec has PureDisk that offers a data deduplication function at the client. IBM is soon to release a similar function in its software product. Other products like Avamar or Asigra have a software...

Are there any standards for server-free or LAN-free backup?
Not so much. Each of the ISVs, the independent software vendors, have their own way of talking to the disk vendors. And each disk vendor has their way of talking to the ISVs. So, if you are an ISV that plans to support server-free backup, there's no single API for you to write to. So, generally, an...

Can you explain the various ways to encrypt tape?
And of course, probably the most ancient form of encryption, is software level encryption. This encrypts your data at the server level or the backup client level and then sends it to the tape device encrypted. Check out the entire Tape Encryption FAQ. The most recent addition is a tape level or device... More... |
