Improvement: backup all but exclude same machines

#1

Could you add in another release this functionality?

It is useful if you have many machines and want to exclude only a few of the backup, instead of put all the names of the machines in the backup command.

Thanks in advance!

#2

This is an easy change and should be included in the next release.

#3

Great!

#4

This feature is now available in version 1.1.0.

#5

Thanks!
