Backup Android SMS, MMS and call log to Gmail / Gcal / IMAP
This is a fork of the now-defunct Android backup tool SMS Backup. It uses Gmail/IMAP to perform SMS, MMS and call log backups over the network. It is important that you perform the first backup manually. SMS Backup+ needs to know whether you want to upload messages currently stored on your device or not. SMS Backup+ can also backup and restore your call logs. It stores all calls using a separate label (defaults to Call log, but can be changed in "Advanced settings"). If you wish you can set this to the same value as SMS, to make all backups use the same label. -
