Use rclone to archive directories of Db data to S3

rclone-bkup-to-s3.sh

#/bin/bash
# rclone-db-bkup-to-s3.sh
# [2018Nov30 mkartha] transfer backups from the /mnt/nas/BackupLinux/ Db pg dumps to S3 using rclone 
# - do this as root from the db-server or a server with rclone in PATH and access to db dumpfiles
# - this script also assumes that rclone has been configured with S3 credentials to transfer data to S3 with rclone profile aws-s3

# skeleton example
#restore_scripts/mkartha/logexec.sh rclone sync ./2018-11-28-daily aws-s3:db-backup/db-backups/2018-11-28-daily/ --ignore-checksum --fast-list --verbose
