Terms:

DRIVE:
A 'drive' is a local storage unit or a cloud storage service where files and data can be stored e.g. Disk drive Dropbox Box Microsoft OneDrive Google Drive Amazon S3 etc.

SOURCE:
A 'source' is a local drive that provides files or data to be uploaded to other drives or receives files downloaded from other drives.


TASK:
A 'task' is a collection of sources with a target drive through which a sync backup or restore operation can be performed.



The app can perform:
* Full Sync: compares and synchronises files at two locations deleted files in one location are deleted at the other while new files at one location are uploaded to the other

* Backup Sync: upload changed files from sources to the destination drive

* Restore Sync: download changed files on a drive to target sources

* FILE MANAGER: list and browse files and folders on a drive upload or download files to and from a drive delete/rename files and folders on a drive.


Usage:
File transfers are performed in tasks and you can create as many tasks for any drive and with as many sources as you prefer.


When you create a task you will
1. add a list of sources that point to the data you want to backup or restore. For files this will be the folder containing the files.

2. add a destination drive and then select a destination folder on the drive where the data will be uploaded to or downloaded from.


Each source in a task can have a 'path'. A source path is a folder name relative to the current task's drive destination folder
where a source's files are uploaded to during a backup or downloaded from during restore.
