contacts backup
please help me to make a backup to my contacts
Your contacts can be backed up using one of the methods provided in this support guide:--> How to back up your iPhone, iPad, and iPod touch – Apple Support
or
You can "sync" your contacts going to Settings>[your name]>iCloud... and flagging (activating) contacts, keeping in mind that if you choose to sync to iCloud, your contacts won't be included in your backups.
