Backup/restore multiple (but not all) packages

e.g.

./backup-app.sh com.nxp.taginfolite  org.kde.kdeconnect_tp user@host:/my/folder/backup
./restore-app.sh com.nxp.taginfolite  org.kde.kdeconnect_tp

The idea is good.
But the solution could be improved.
I suggest using file such as applist to use as input
There is apps available that list files in specific formats. The output can be edited then used.

  So, command would be:

./backup-app.sh applist user@host:/my/folder/backup

As a minimum, applist would include package names of all apps you want to backup, one per line.

This could be realized like so:

./backup-app.sh $(cat applist) user@host:/my/folder/backup

without having to implement file loading or parsing 😉
