The older systems...If I recall would go for 30 days or something crazy.
Now I think it is a week tops if you are lucky.
Better count on about 4 days or less.

Hi all,

I did a little googling, but after nothing came up in the first pass I thought I'd see if anyone knew off the top of their head: how long can a nvram battery in the current generation of storage systems protect data w/o power? In other words, how long can a system remain down before the data goes kaput?

Thanks in advance,
Nick
