My projects on GitHub are more like a tutorial than a finished product: bestia-dev tutorials.

OBSOLETE

This project was made with "egui immediate mode GUI", but I don't really like that.
I will rewrite the project with "iced retained mode GUI".

Backup

My friend has a laptop with 1TB space for his data.
Then a super tiny and extremely fast Samsung T7 Shield 2TB external SSD as primary backup.
And then a big old 2TB external HDD as secondary backup. It is so big that it has it's own power.

The difference in storage size makes the backup tricky. Not impossible, but a notch more complicated that he would like.

I was thinking of using robocopy for the backup, but as always it lacks a feature that I would like to have. When the files are deleted on the original disk I want to save these files on the backup disk for possible recovery later. Robocopy just delete them. I know there exists the windows recycle bin, but I don't want to use that.

First the program will check what disks are connected. The names of the folders are fixed so I can recognize them easily. There are 3 different backups:

  1. from the laptop d:\original1 to e:\backup1_of_original1
  2. from the laptop d:\original1 to f:\backup2_of_original1
  3. from the primary backup e:\original2 to f:\backup_of_original2

The files that should be deleted will be moved into a folder named deleted_on_backup_datetime. This can be reviewed and finally manually delete when not needed any more.

I will use robocopy to list the files to be deleted. Then I will parse the output and move these files. Then I will use robocopy to make a "mirror backup". Sounds easy.

GUI for windows

My friend is not a computer guy, so I decided that a CLI program in a terminal is not for him. He is comfortable to use GUI programs in Windows.

I experimented with the crate egui to create a super simple GUI program for Windows, but I don't like the "immediate mode GUI".
I will rewrite it using "iced retained mode GUI".

Cross compile to windows

On my machine I have Windows11 with WSL/Debian. I will cross compile to Windows, copy the exe file with scp and run it on Windows.

I use cargo-auto for automation of the build process and to commit to GitHub. Just run cargo auto and follow the instructions. To work with GitHub it will need the Personal Access Token from https://github.com/settings/tokens.

Copy the exe file from the container 'crustde' to win folder. Run in windows git-bash:

scp rustdevuser@crustde:/home/rustdevuser/rustprojects/backup_for_zeljko_egui/target/x86_64-pc-windows-gnu/release/backup_for_zeljko_egui.exe /c/Users/Luciano/rustprojects/backup_for_zeljko_egui/

# then run in git-bash
cd ~/rustprojects/backup_for_zeljko_egui
./backup_for_zeljko_egui.exe

Robocopy

Robocopy stands for "Robust copy" in Windows. It is good.
First I want to list the files that should be deleted.
Then I will parse the output and move these files instead of delete them.
In the output I must recognize the files that start with the destination folder.

robocopy options
/L :: List only - don't copy, timestamp or delete any files.
/X :: report all eXtra files, not just those selected.
/FP :: include Full Pathname of files in the output.
/NS :: No Size - don't log file sizes.
/NC :: No Class - don't log file classes.
/NDL :: No Directory List - don't log directory names.

robocopy d:\original1 d:\backup1_of_original1 /MIR /L /X /FP /NS /NC /NDL

The output is terrible to parse:
