Pi backup question

[chili]

made quite a few errors messing with my raspberry pi 3b, my question is once i have it running the way i want it too what is the best way to backup the
sdcard so if i do make a balls up i can just write the saved image to it?

thanks

 

[chili]

use something like etcher to clone the sd card

cool thanks for that, so i clone the card and if it goes **** up at a later date i use raspberry pi imager and write custom image or i use etcher to write aswell?

seems the write process completes but the card will not read/boot once inserted in the pi?

So i used win32 disk imager to read my sdcard and make an image, then i wrote the said image to another sdcard the same size etc to see if the process worked. The write completes but when i put the card into the pi it just sit's there on a red light no flickering green activity
light from the pi.
i am doing this on windows 11 home and the pi is a 3b+

Update, just booted direct into the pi desktop and used the sdcard copier in that and it worked a treat.
