Right now my network storage is Western digital 1TB X4 for redundancy, they are sitting at 12% use. 1 external hard drive and I also make use of USB thumb drives 8Gb. I keep them small due to cost and because i put data to them and then soft lock it "make it read only" once done. They are for once off use so i don't reuse them once the data is on and the drive is soft locked it becomes a ROM in my eyes. i know i can add more but the cost is very low so this is not a problem.Agreed.....that IS the important part
Just out of idle curiousity, what do you use to backup?
My other backup for the LAN storage is blu-ray external writer and i use 25GB disks. In all honesty i have used maybe 2 Disks so far. I do not write on the disk more then once so basically i make a "new" backup on the disk each time.
Now to note this is not because i am paranoid but theft is a big big problem. So it is easy to store blue-ray disks so even if my office gets cleared out completely i can still recover everything. All my backups are Zipped and password protected.
I use 7Zip for this, i know some users had a bad time with 7Zip but it works for me personally. So even if someone grab everything all they get is flash drives they can't easily format and hard drives filled with Zip files that are password protected. My version of 7zip support the AES-256 encryption method.
It is also why i have a dedicated "older computer " to Zip and store my files. It can take a while. But cool thing with Zip files is you can actually chop them up into a size that makes it really handy for smaller size thumb drives especially.
just to add i have 2 re-writable disks that i use for monthly backup but the other disks are long term backups i don't do many of them because i feel the re-writable disks are reliable BUT i make backups every few months using normal writable disks. But i only had the writer for a few weeks now so it hasn't seen much use yet. i replaced my DVD writer with it as it is a lot less that i have to store physically.
