3-2-1 Backup Scheme Example

        1                2                         3
[Primary Directory]->[External Drive]->[Cloud Storage]
        |                ^        |                ^
        |                |        |                |
        [<=backy========>]        [<=Cloud App>===>]

For a complex backup schemes it is highly recommended to split tasks to separate configuration files and time periods. Another tip is to chain your backup actions by backy exit codes.

Exit Codes

• 0 - Synchronization and archiving completed successfully
• 1 - No task configuration provided
• 2 - Can't read provided task configuration
• 3 - Synchronization completed with errors
• 4 - Archiving completed with errors
• 5 - Synchronization and archiving completed with errors
