Like many other members of the geek brotherhood, I provide informal tech support services for my friends and neighbors. In return they take care of Dr. Humphrey D. Dogg, DCS (Doctor of Canine Studies), when I fly off to Interop or TechEd. A few weeks ago one of my dog-run buddies was lamenting the lack of a good backup program for his Mac that would save his data to recordable DVDs. Given that he had an older PowerPC-based Mac and couldn't run Time Machine, I didn't have a better answer for him
Monday at its EMC World conference, EMC announced a line of three deduplicating backup targets that are the product of its long-rumored collaboration with Quantum. While the 3D disk libraries bear some resemblance to Quantum's own DXi line, EMC has done more than just OEM Quantum's product. In addition to using EMC Clariion disk arrays, which gives them greater scalability, and RAID 6 for enhanced reliability, they use Western Digital's GreenPower 1 TB drives that draw half as much power as stan
Do you rely on your road warriors to backup their laptops? Is that working out for you or are you just blaming the victim when they're machines are lost, stolen or just break down after being sent through the airport X-ray machine one time too many? Once you accept the fact that users, especially Sr. executives won't take any action at all to backup their data on a regular basis you'll start looking for an automated solution. Atempo's Live Backup has been that automated solution for Windows f
As I talk to vendors about storage solutions for non-OLTP applications, from backup and archiving to supporting massive, object-based Web applications like photo sharing, I've been seeing more solutions based on the RAIN (Redundant Array of Independent Nodes) architecture.
In what seems to me to be kicking a perfectly good supplier when it's down, Beth Pariseau at SearchDataBackup.com reports that IBM stated that FalconStor's SIR deduplication add-on for their virtual tape library didn't make it through the validation process. Given the fact that IBM recently bought Diligent Technologies for its ProtecTIER deduping VTL software, it's no surprise that someone at IBM wasn't convinced that Single Instance Repository, or SIR, was the best thing since sliced bread.
VMware announced this week that its Site Recovery Manager would be available to real users like you, dear reader, next month. Click here for our crack InformationWeek news department report on the announcement. From where I sit, Site Recovery Manager could be as big a game-changer for SME disaster recovery planning as server virtualization itself.
The DD690 device boosts the vendor's claimed data ingestion and deduplication rate to 170 Mbps for a single backup stream and to 388 Mbps aggregate for multiple streams
It should be clear to most of us by now that server virtualization changes the disaster recovery game dramatically. Rather than having to maintain a server at your DR site for each server in your production environment, you can replicate physical, and/or virtual, servers from your production site to virtual servers at your DR site, reducing the cost of protecting production systems or increasing the number of servers you can protect.
A few years ago it was easy to divide IT organizations into haves and have nots. The haves used Fibre Channel SANs and array replication to dedicated disaster recovery sites over high bandwidth dedicated links or dark fiber. The have-nots used SCSI DAS (Direct Attached Storage) on their servers and, if they did real time replication at all, used server-based replication solutions like Double-Take or CA's WANsync.
While heavily regulated and leading-edge organizations use dedicated systems to store their archival data, if you asked most IT managers where their archives were they'd point at a shelf of old backup tapes or the logbook of tapes at Iron Mountain. Similarly, legal hold meant taking a group of tapes out of the rotation and putting them on the shelf. When someone actually wanted all the documents and e-mail messages related to "The Incident," some poor backup boy had to restore all those tapes an
