Environment variable backup

[2217092594]

I believe adding a backup feature would be a good idea!

The situation is like this: I have personally implemented a similar feature, but due to my limited skills, it caused all of my system's PATH environment variables to be lost. This resulted in a significant loss of time and effort for me, so I can deeply relate to this issue.

As for the trigger for backups, it could be whenever there is a change in the variables or scheduled backups. The backup methods can include full backups, incremental backups, or differential backups. However, in the case of Java environment variables, I think a full backup mode would suffice since it wouldn't occupy too much space.

The above is just a small suggestion from my side. I hope to receive a response regarding this matter.

This sound useful and will be implemented in jvenv the successor of jenv
