If you need a place for your backups - why choose HostGator?
I must say that "unlimited" disk space and bandwidth sounds nice but that's just an overselling term they use. It's not unlimited.
Anyway, if you're looking into reliable backup solution check the
Amazon S3 or
DigitalOcean spaces...
There are many similar solutions (
Google Cloud Storage,
Microsoft Azure Storage...) and with these you only pay for what you use. Prices are cheap and many will give you one or two months for free.
