backintime-qt4 1.1.12-1 (arm64 binary) in ubuntu xenial

 Back In Time is a framework for rsync and cron for the purpose of
 taking snapshots and backups of specified folders. It minimizes disk space use
 by taking a snapshot only if the directory has been changed, and hard links
 for unmodified files if it has. The user can schedule regular backups using
 cron.
 .
 This is the graphical interface for Back In Time.
