How to implement snapshots
It can take up to 12 hours or more to process a full backup job and move the entire backup volume to tape or disk. For many companies, that's just too much time. IT departments can use snapshots to capture entire storage environments, or simply track changes to the state of mission-critical systems. Snapshots can establish...

How to implement disk-to-disk backups
As capacities grow and costs per gigabyte shrink, disk is being used as a backup storage target more frequently. Disk offers far better performance than tape systems, allowing for faster data transfers as well as greater long-term reliability. Disk can accept complete backup volumes, as well as simple file copies. For example, backup software...

How to improve tape backup performance and reliability
The role of tape is clearly changing, shifting away from everyday data backup and moving toward deep archiving or offsite storage, but tape is still an important element of many data centers. Storage professionals must contend with concerns about tape performance and reliability that have remained almost unchanged for decades. In spite...

How virtualizing servers has impacted the backup process
However, in some cases server virtualization can reduce the number of backup licenses. This is a nice benefit. You don't have to run as many agents as in the past, and you can save some money there. In some environments, server virtualization has prompted the use of a secondary storage system, for example, a disk-to... More...
What type of data reduction ratios should you realistically expect using deduplication?
at it. Most people are looking at data deduplication in conjunction with backup; backup appliances performing deduplication or even virtual tape libraries (VTL). So, looking at it in that context, you'll hear advertised ratios of anywhere from 10 to 500X.
But, realistically, I think it's safe to assume a ratio of... More... |
