Backup Disk
Read full descriptionHide full description
Backup Disk is a utility that turns iPhone and iPad into a reliable backup device for your Mac. You can easily back up selected folders on your computer by syncing them with your device wirelessly. The app can detect files that have changed and only sync them, so your periodic backups will run much faster. Copying large numbers of small files between disks has always been problematic. The app's algorithm allows these files to be combined into larger packages and transferred between devices. Thus, it makes much faster and more efficient backups. If the backup process is interrupted for any reason, the next operation can continue from where it left off. SUBSCRIPTION If you choose to purchase Backup Disk PRO by a subscription option, payment will be charged to your iTunes account, and your account will be charged for renewal within 24-hours prior to the end of the current period. Auto-renewal may be turned off at any time by going to your settings in the iTunes Store after purchase.
