Backup Media.
Backup Media, must be reliable cheap and effective and let us not forget that data is not getting smaller. Thanks to the new Terabyte HDD we have more data on our systems than ever before. Now if this Terabyte HDD where to fail then you will lose a hell of a lot!
Now you will say that no matter we have Blue-Ray aka “Blu-Ray” that gives you up to 50GB of backup capacity and we will soon see even bigger disks! However the cost of maintaining a Blue-Ray is not cheap and I am questioning its sustainability. Right now we use external HDD and DVD to backup Data.
However DVD’s can be easily corrupted and HDD can crash so the best bet is to Keep two HDD going with a DVD as a redundancy backup. This way you can recover data.
Also thanks to servers and RAID makes data bit harder to lose and thanks to active-directory you are safe. However all has its limitations and even a powerful Raid Server can fail...
So the key to any good backup system is redundancy. N-as aka “Network-attached storage” is also not bad but your network needs to be able to support it properly.
Now I am interested in your backup systems. What do you use? And why do you think it is safe?
