The trouble with "free" services is that they could go away (or the terms could change) at any moment.
Hard drives are cheap...
Perfect response. I don't trust someone else to keep data that I value. As soon as mediafire's main financial sponsor's are gone, so is mediafire and there goes your data.
Lots of people say harddrives can't be trusted because they fail, but this isn't thinking big enough. You need to think beyond a single harddrive backup system. The most effective data backup employs redundancy in sources and locations, and employs frequent backups.
Ask yourself this, if you spend $1000 plus on gear to capture an audio recording and you record any number of performances yearly, isn't it worth another $200 to buy redundant 1TB harddrives to effectively store the data? I think it is.
I have 4 or 5 hard-drives. I have all of my audio masters on one external drive that's sitting on my machine at home...a second drive mirrors the first drive and that one is sitting on my desk here at work. I get about one failed drive per year. When that happens, I simply go out and buy a new one and then re-back-up whatever is needed.
The key is to NEVER NEVER rely on a single drive to store all your important data. That's just like inviting Murphy to take a shit on you!
