What is the SD or CF card lifetime in LMs? How Can I prepare for fast exchange this card? How Can I extend its lifetime?

We expect the card to work for at least 10 years. LM is optimized to minimize the amount of writes, most frequently used files are stored or cached in RAM. You can make a full disk image to quickly restore it, but you will have to open the enclosure and remove the card from the device. Or you can use backup and a restore image, but then you won't have some configuration files like network config etc.

Very good and helpfull answer. For me it is very important to give this information to client because when there will be some problems because of card will crash client will know this and will know that there is nothing very bad but only rare maintenance. ThanksWink

The "Backup and restore image" functionality, is this the standard "backup / Restore" buttons visible under the "Utilities" root? (Schneider Wiser)
This is Exporting a file called "Project-WiserKNX-2020.01.05-19.09.tar.gz"  With filesize at 279kb?  is this the full image/backup file?
Schneider Wiser (homeLynk), DALI controller, Actuators and Multitouch Pro buttons. Panasonic Heating pump, Flexit balanced ventilation. Lemus Speaker system.

This is the full project backup yes, It does not contain the System part. This can be backed up separately under System

Unfortunately on one of my LM SD card died today after four years.

So it can happen.
