What is snapshot, why do I need it?

December 19, 2011

Currently, most storage providers use this technology called Snapshot. This technology uses a method called “Copy On Write” which means that, if a location is changed, old data from the time snapshot for that location is stored in a repository called SnapSpace. The consequential snapshot will look like an actual volume, containing data at the time of snapshot taken.

Snapshot is also called Shadow Copy in windows Terminology. But the difference between windows based shadow copy and storage based snapshots are that windows based shadow copy will take the CPU cycles of the server, but storage snapshot does not.

Why do I need it?

Below listed are some usages of Snapshot.

–       Backup: Take a snapshot, backup the snapshot.

–      File Recovery: In case a file is deleted accidentally, it can be retrieved by going back to the snapshot.

–       Take a snapshot, give that to one or more other groups to work on it, while live volume is changing.

MDA switches to StoneFly’s IP SAN to expand and revamp data backup procedures

December 13, 2011

Medical Doctor Associates (MDA), involved in providing quality medical staffing to the healthcare community recently faced issues as their entire data center was dependent on a FC- SAN.  Large amounts of data being processed on a daily basis demanded much superior data backup as well as storage procedures.

The problem: Apparently, MDA’s IT department deliberated a switch of their data from their fiber channel network to a backup tape. This process was inadequate and could not meet time constraints. Another issue that cropped up was the insufficient options offered by fiber channel storage, making data storage less scalable. All this led them to switch to a three phase plan to achieve their expansion in data storage.

Approach used to get the desired solution used the three phase plan to transfer data, explained in simple terms below:

Phase 1.  Migrate pre-existing files by creating a disk to disk (D2D) backup. – uses StoneFly’s ISC 2402 S-    Class IP SAN.

Phase 2.  Achieve scalability by using StoneFly’s ISC- 2402E S- Class Expansion unit, using RAID 6, for storing data involved in applications.

Phase 3. Performance enhancement, using StoneFly’s ISC -2402 E S- Class Expansion Unit with SAS 6g RAID architecture.

StoneFly’s IP SAN storage is a good choice in providing a solution to MDA’s problem due to the following key factors:

  1. Versatility of appliances.
  2. Ease of data management
  3. Advanced features that could not previously be achieved with Fiber channel storage.
  4. Reasonable pricing.

For more details about the products used for this type of storage, Please go to StoneFly’s IP SAN products.

It’s All About Restore

November 10, 2011

Peace of mind comes from knowing your backed-up data can actually be restored quickly and reliably. Backups can be easily verified, but there is high anxiety associated with confirming
the reliability of a restore.    In most cases, knowing that a restore actually works usually occurs after data is lost. Keeping your fingers crossed should not be an integral part of a data recovery program.

High profile events, such as recent natural disasters, provide harsh reminders of the many ways information can be lost. Among the most common are hardware and software malfunction, human error, computer viruses and natural disasters.There are three main quantifiable costs associated with each incident of data loss:  the cost of technical support in the recovery effort, lost productivity due to user downtime, and the possible cost associated with data that is permanently lost.

Visit StoneFly Whitepaper Library to learn all about cost-effective restore suggested by experienced StoneFly experts.
