I'm going to say yes, because it more easily protects against drive failure without needing more hard drives. I'm backing up around 2TB from my server.
CrashPlan also does unlimited revision backup and long lasting deleted files. Not that that is massively useful, but I do nightly full image backups of some of my important RPis, locally I store 7 days worth, but CrashPlan must have months/years of these now I could recover. An absolute waste of space, but it's unlimited so ¯\_(ツ)_/¯
It also means that I've not had to pull my finger out and organise my storage, which I desperately need to. I've just pointed the software at loads of folders and left it to it.
I decided against backing up TV and Movies. But definitely music.
I think I'll look at what you've said, because local backups are obviously significantly quicker to restore. Maybe for absolute essentials. I used to backup locally, but rather than having a backup drive, as such, I backed up bits across various other drives.
True. I've had to recover from many a dead hdd, no fires/floods/nukes thus far (though I can see nukes from my balcony and we get plenty o' floods, none have reached the 13th floor, thus far).
