Is it safe to upgrade without backing up hard drives first. I don`t fill like backing up 1TB of files.
I know Dlink recommends backing it up first. I did it before and didn`t loose any files.
In the words of Clint Eastwood's Dirty Harry - so tell me punk, do ya feel lucky? Well - do ya?
Without a backup, your data is at risk, even if you're not doing a firmware upgrade and just using the NAS normally
Without a backup, your data is at even greater risk, whilst you're doing an upgrade - if you don't want to follow good advice, then don't ***** & gripe when disaster strikes.
It's your data - if you have no value for it, you figure we care?
