You have to specify destination folder, this can be a mounted network folder or a folder on a external usb drive. And of course, it would not make sense to store a image backup on a medium I make the backup from.

Quote:So let me see if i understand this correctly. Using the make an image option, i will get a fully flashable / ready to use image of all of my current installation (all partitions, settings etc including the boot partition). All i need is to set LZO and reboot then make the image, etc, etc , etc currect?

Not all partitions, all volumes in the root file system. Additional partitions (for example swap partition) are not included
And, if you have a special configuration which differs from the standard (for example running NOOBS/PINN, or having root fs or /home on external disk/usb stick, it is much more complicated and is not supported by building backup image

Quote:Two Last questions:

If i change the compression to LZO (its set as LZ4) will the system still boot? If so then:

Hey, it would not make sense to write "switch to LZO compression and reboot" if reboot would not work

Quote:After i re-flash the backup image and since i'm still below kernel 4.15, will the system revert back to LZ4 again or the " zswap.compressor=lzo" setting will prevent that?

Also is it a O (letter) or a 0 (zero) on LZO, and is it case sensitive?

Ohhhhhh, and it's case sensitive, as usual. And no, there are no gizmo's in the system which switch back to LZ4: This would make the whole procedure ad absurdum
