I had a few D1 Minis lying around that I wanted to flash WLED onto. But when plugging into my main PC running Linux Mint 21, no device got recognized. The D1 Mini was just flashing its blue LED light 2 times and that was all. I had already checked before, whether the USB cable is also a Data Link cable, because now and then you accidentally grab a USB cable which is charging only.
Since I was pretty sure it wasn’t a hardware problem, I checked dmesg for any suspicious messages. I’m using an alias named klog to beautify the output.
In January 2020 I bought a Sharkoon PureWriter Keyboard and since then I had the problem that the keyboard got not recognized after my PC (which runs on Linux Mint) was coming back from suspend mode. Back then I couldn’t find a solution and was just hoping that a newer kernel release will fix this problem in the future. But it did not. So today I was searching again and stumbled again across this post, but now I noticed the new answer from April this year. And it finally solved it!
This is equivalent to -rlptgoD. It is a quick way of saying you want recursion and want to preserve almost everything.
-z –compress
With this option, rsync compresses the file data as it is sent to the destination machine, which reduces the amount of data being transmitted
-P
The -P option is equivalent to –partial –progress. Its purpose is to make it much easier to specify these two options for a long transfer that may be interrupted.
–delete
This tells rsync to delete extraneous files from the receiving side (ones that aren’t on the sending side)
–exclude
exclude files matching PATTERN
-b –backup-dir
With this option preexisting destination files are renamed with a ~ extension as each file is transferred. You can control where the backup file goes and what (if any) suffix gets appended using the –backup-dir and –suffix options.
But somehow it always created the Backup folder recursively again inside the Backup folder. So the first run created the /Backup folder, after the second run I’ve got /Backup/Backup, after the third run /Backup/Backup/Backup and so on..
The solution was to exclude the Backup directory using the --exclude command.
“If we are storing backups in the destination folder, or in a directory inside of the destination folder, the --delete parameter is going to delete old backups, as they are not in the source folder. Or attempt to as in the following situation:
Say, we already have a folder called backup inside of the destination directory, and we use rsync again, using --backup-dir=backup one more time. As rsync is going to attempt to delete every file and folder that is not in the source directory, it would backup the backup folder, which would create a backup folder inside our already existing backup folder, and then it would attempt to delete the backup folder and fail because it is using it to backup files.”
“Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. With ventoy, you don’t need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly.”
