Backup and Restore a PDMM or PCMM

The SD card is used for backing up and restoring the data from a PDMM or PCMM.

Backing up may be performed in either of two ways.

Using the web server, which is recommended as it has functionality the button method does not offer, such as backing up the drive data. For more details, see Backup & Restore from the Web Server.
Using the PDMM or PCMM B3 Button Menu on the front of the controller. See Backup Using the B3 Button for more details.

For a complete backup of both the controller and drive, use the Web Server backup.

Restoring information to the controller may be performed in either of two ways. Both methods restore the controller (and PDMM drive) with whatever was saved to the SD card.

Using the web server. For more details, see Backup & Restore from the Web Server.
Using the B3 button menu on the front of the controller. See Restore Using the B3 Button for more details.

About the data transfer

The 7-segment display will show the chasing lights animation while the backup or restore is occurring.
The Backup and Restore functions have an "all or nothing" behavior. If there is no SD card inserted, if there is not enough space on the card or if files are missing then nothing will be copied and the 7-segment display will show an error.
If files already exist on the SD card (in the backup directory), then they will be deleted and replaced with the new PDMM or PCMM backup configuration files. Likewise, the files on the controller will be replaced with the SD files.

Warning! Do not modify the files on the SD card as this could result in the Restore function failing.

If you have multiple PDMM or PCMM backup configurations, you will need to use one SD card per backup configuration.
