BAD!
Dont ever use Ibackup, besides supper slow software that will use tons of resources, small tech support group, they will get you this way:
You sign up for a contract lets say of 100 G. for 10.00 Dollars; The next plan is 20.00 dollars for 250 Gigs. So you are not there at the time.
After 3 months your business grows, and you need now to backup 150 G.
You get an email your out of quota, I mean dont panic, you know you will have to upgrade your plan to the next level of $20.00
No problem correct?
Wrong!
You will be charged insanely instead of going to a new contract.
Sorry Ibackup two thumbs down.
