ressu/periodic-rsync

Docker container to run rsync periodically

Periodic rsync container

Due to a bug in Synology Active Backup, I created a container to sync a given directory periodically.

General

For this container to work, we need to mount the local data source to /data and set either SOURCE or DESTINATION

docker run -v /storage:/data -e PASSWORD=Insecure -e SOURCE=user@server.net:/source ressu/periodic-rsync

Environment

This container takes the following environment variables.

SCHEDULE

This variable contains a standard cron schedule, for example 0 * * * *

PASSWORD

The SSH password used to login to the SSH server.

SOURCE

Source address for rsync copy

SSH_OPTIONS

Override default SSH options. By default set to -Tx, which disables terminal and X forwarding

DESTINATION

Destination address to copy data to.

Directory for temporary files

Sometimes it's needed to have temporary files outside of the transfer directory. Creating a directory named .temp in the filesystem mounted to /data, will use that directory to store temporary files during transfer.
