#!/usr/bin/env bash
# ------------------------------
# Backup and store encrypted backup in safe place.
#
# Generally, there are two approaches to backup process: full backup of all targets each time and incremental of some sort.
# When the amount (and "volume") of targets is relatively small may be it's simpler to just backup all targets and store, for example,
# three last blobs.
#
# Specials:
# BACKUP_STORE - where backup should be stored
#
# Example: ./backup.sh <target_1> <target_2>
