How much space does an iphone backup take?

Hi,

95GB's of free storage space isn't really sufficient. Window's runs about 16GB's > https://www.microsoft.com/en-us/windows/windows-10-specifications#sysreqs

Mac about 9GB's.

If an alert says there's not enough disk space

If a message says there’s not enough disk space when you try to back up your device, free some space on your Mac or PC. If you still see a disk-space error after you free enough space, contact Apple Support.

An iPhone backup does not include apps and music, and anything synced to iCloud (Settings/iCloud - all the switches that are on) so subtract those from what is on your phone and the rest will be what is in the backup.

You will also get that error if iTunes does not have write privileges in the backup directory. See: About backups in iCloud and iTunes - Apple Support

Attempting to sync my iPhone 5SE running 10.1.1.

This may have been the first time I synced since updating to latest software.

I got error message that iphone couldn’t be backed up because the iphone disconnected.

Did a hard reset on the phone and changed USB ports on my iMac.

Then got message that my computer didn’t have enough space for backup when it has 225GB.

Restarted my computer and tried again only to have the error message say that the backup was corrupt or not compatible with the iphone.

I then opened my user library

Open Finder, holding the option key, select <Library> from the Go menu to get to your user's Library folder.

/Users/your username/Library/Application Support/MobileSync/Backup

I renamed the folder <backup> to <oldbackup>

I reconnected my iphone and selected <backup now>

Backup was completed successfully.

I don't think you need to do all the preliminary tasks I attempted.

Go to your user library

Good luck!

Backups are incremental, except for the first backup after an iOS update. However, it needs temporary staging space on the drive during the backup.
