Six Reasons You May Not Be Reaching Your Maximum Tape Drive Capacity

Most tape formats detail the maximum local capacity (without compression) and the maximum compressed capacity. These figures are approximate maximum capacities for the tape drive and these maximums are got under great conditions.

Because real-world systems barely meet great conditions, you may not be able to achieve the specified maximums. As an example, the type of information you are attempting to compress has a great effect on capacity. Some kinds of data just don't compress well.

If you are seeing noticeably lower capacity, it may be due to a few of the following reasons:

The tape drive’s data compression is not enabled. Tape drives that compress information use compression by default. Nevertheless there are techniques for tape drive compression to be turned off through the backup application. Take a look at your application to determine if it has got a setting for hardware compression. In most situations, you will be wanting to make sure hardware compression is turned on.

You may be writing info that does not compress well.Maximum capacities for tapes are typically based primarily on a standard 2:1 info compression proportion (or 2.5:1 for Exabyte M2 drives and some Sony AIT drives). Some types of information compress at a higher ratio; others compress at a lower proportion. For example, executable files and graphics files usually don't compress well.

The tape drive might be attempting to compress information that's already compressed.If your backup programme compresses data before sending it to the tape drive, the tape drive can't compress it further. Actually the extra attempt at compression may actually cause the information to expand. Don't use both software and hardware info compression. If the tape drive is about to compress data, switch off the software compression in your backup application.In the same way, compressed files on your hard disk won't compress any further when fed through the tape drive’s hardware compression chip. If you're backing up a high share of already compressed files, such as MP3, AVI, and JPG files, then you will not see any farther compression at the tape drive level. In fact , as the information is compressed twice, it may very well expand. Try turning off hardware compression and software compression in your backup application.

Your system may struggle to stay abreast of the tape drive.If your PC does not send information to the tape drive as quick as the tape drive can write info to the tape, the tape drive stops and waits for the computer. Everytime the tape drive stops, it writes gap tracks (tracks of uncertain data) to aid in repositioning when more info becomes available. If the tape drive has to stop and restart frequently, tape capacity is affected. Check if there are transfer bottlenecks in your system. As an example, if you're backing up info over a 100bT network, a common transfer rate could be much more slowly than you are expecting. In this situation, converting the network to at least 1GbE and for should improve both transfer rates and tape capacity. For the latest servers and LTO5 drives, a full 6Gb/sec should be provided to the tape drive.

Your tape could be ready for retirement.If you use a tape that's well worn, the tape drive might be performing high numbers of rewrites to correct errors. Excessive rewrites reduce the tape’s capacity. Try cleaning the tape drive with the correct cleaning tape for your machine employing a new tape, and ensure you are using good quality info cartridges.

Your tape drive may need to be cleaned.A buildup of debris in the tape drive or on the recording heads can lead to increased mistake rates and rewrites. If you haven't cleaned your tape drive recently, try cleaning it with the right Cleaning Cartridge for your tape drive model.

Why Is Data Storage So Vital

When purchasing a new computer, one of the first things that people look at is the memory size. You wish to make sure that you have sufficient room to store your music, photographs, and whatever other data you plan on storing on there. If you're on the ball, then chances are high that you will make certain to transfer all your crucial stuff to disk or flash drive, making certain that all of your stuff is safe should some catastrophe strike your P.C. It isn't difficult to stay on top of your data storage on a home computer, but it gets a touch more tricky for companies that could be in real trouble if their network becomes somehow compromised.

What may be a surprise is that the tips that data storage experts would give to home computer users also apply to firms massive and tiny. That all starts by making absolutely sure that your data is arranged in a way that is easy and tidy. Attempt to name folders in a fashion that will help you immediately recognize what is contained inside each and try and organize everything alphabetical, chronologically or by subject.

Another large part of remaining arranged is making certain that you keep mess to the minimum. There will be files and folders that are not required after time, so why have them use up space on your PC. You can opt to remove them or store them outwardly on disk or flash drive, just in case they must be accessed later. That may help unlock space on the computer and make it run faster and smoother. You should also look at defragmentation as a part of the clean-up process as that will make it way easier to recover data from any computer that has got a failure of some sort.

It’s mankind's nature to get a little cushty when a new computer is brought into the business or home. New PCs are not completely free from the probability of issues, so make certain you frequently back-up all your important data. How regularly you decide to do so really is dependent upon how much data is added to your computer during any particular time period. Some might find it critical to back-up on a regular basis, while others might only need to do it on a weekly or monthly basis. Whatever the case, make a back-up schedule and keep it up.

Setting up a regular maintenance schedule will give you the best probability of keeping your data secure and intact, but you must also be a little vigilant. That suggests making sure that you have a professional antivirus and security set-up in place , as well as keeping an eye fixed on your personal computer for potential issues. A personal computer will customarily give you some danger signs that it’s about to fail or has been compromised, so don’t wait for the worst. The 1st sign of anything weird should have you seeking the help of an IT professional.
