We wanted a way to back up our office systems remotely as well as locally, and looked hard for a cloud-based system That could handle a number of devices and operating systems.
We found iBackup, and now recommend it to our clients. iBackup is an enterprise class system that works with PCs, Macs, and Linux machines. You can access your files from mobile devices as well as desktops.
Your data is encrypted with 256-bit AES encryption, and both uploads and downloads are encrypted as well.
You can restore the last 10 versions of files backed up on your account. That allows you to recall a good copy of a file that had been damaged locally.
IBackup gives you lots of disk space at an affordable annual or monthly price. See their current offerings here. You can protect your business with 500GB of cloud backup for just $9.95/month.
