Data Storage Systems Nexsan

It's amazing how cheap data storage is these days. Ten years ago I received a 64mb thumbdrive from my boss for Christmas. They were fairly new at the time, so it was a really big deal. It was a pretty cool little device to save a few files on. lol. Nowadays, thumbdrive sizes are in gigabytes rather than megabytes.
I have a 250gb external hard drive that I need to upgrade someday, since you can now buy one with available space in terabytes.
Cloud storage is a great storage option since you don't have to worry about having a physical device to store the data on. You can also access the data from any computer, provided you have an internet connection. There are quite a few web sites out there that offer a certain amount of free cloud storage. Amazon even offers 5gb of free cloud storage.
There is a company called Nexsan that offer huge amounts of high end storage. They sell Flexible Storage Platform systems which may contain between 14 and 60 drives and can be expanded with additional units. The NEXSAN E5000 family of data storage systems can hold up to 720tb. That's a lot of data. Drives use Nexsan's anti-vibration design, cool drive technology and active drawer technology.
Nexsan also offers web-based storage system software with features such as disk provisioning, RAID hardware management, host data path services and automatic RAID set rebuild.
Nexsan's storage application software includes features such as file services, snapshot, replication and archiving to storage system hardware. Archiving services id files for integrity, store two copies for added protection, continuously repair files, use WORM on disk, and provide data encryption and key management.
Nexsan was formed in 1999 and are based in Thousand Oaks, California.
Back up's are really important. You never know when a disaster might happen and your data will be wiped out.
The other day I was working on a file in PHP. An example file I was following contained a call to unlink. Unlink was an unfamiliar function to me, but I found out the hard way what it does. Since the example file I was using called it, I included it in my test file. I ran my test file, and it suddenly disappeared. Yeah, unlink deletes a file. Luckily I was able to recreate my test file without too much trouble. I also downloaded an application called Recuva. After doing a deep scan and running all day, Recuva found the unlinked file, and I was able to restore it.
