Hi,
Hope this is the right area for this.
I take a nightly backup of my sd card to disk, but also want to do a weekly clone, just in case it fails totally.
I have a cron job that runs, but I'm not sure if it's doing what I want after the first time it was run.
The command is :
sudo dd if=/dev/mmcblk0 of=/dev/dev/disk/by-id/usb-Mass_Storage_Device_"SerNumber":0.
The output disk is /dev/sdc but I used its ID to stop it overwriting any SD card I was stupid enough to leave in the reader if I forgot.
The output I get is:
Method: ddfull
Device file: /dev/root
Root drive: /dev/mmcblk0
1+0 records in
1+0 records out
446 bytes copied, 0.000312293 s, 1.4 MB/s
1+0 records in
1+0 records out
512 bytes copied, 0.00020172 s, 2.5 MB/s
Boot drive: /dev/sdc1
Using dd full disk...
Backup works and produces a bootable SD card, but my concern is the 2nd to last line, is it saying that I'm backing up from my backup SDcard bootable section over itself?
Many thanks
