Backup SSH - Escaping / at the end

[Bischi1997]

Versions: OS: CentOS 7.5.1804 Webmin version: 1.900 Usermin version: 1.750 Virtualmin version: 6.04 Authentic theme version: 19.21

Steps to reproduce:

1. Create a new backup to an SSH Server.
   • All Virtual Servers
   • All Features
   • SSH Server with the following settings:
   • For the path enter something like "/backup/%d-%m-%Y-%H.%M/"
   • Delete old backups: yes, 30 days
   • Do strftime-style: ticked
   • One file per server
   • Full backup
   • Simple Schedule: hourly
2. Save the newly created scheduled backup
3. When you now check the entries again, you get "/backup/%d-%m-%Y-%H.%M"
4. When you now run the backup job you will get this error: .. upload failed! user@server's password: /backup/29-11-2018-13.00/example.com.tar.gz.info: Not a directory

In step 4. the directory "backup" is created. However since the "/" at the ending is escaped, virtualmin creates a file instead of a directory.

It is possible to create a backup if I select "Single archive file" instead of "One file per server".

The trailing slash should get automatically removed when creating a backup like this, which should cause Virtualmin to create destination directories matching /backup/%d-%m-%Y-%H.%M (unless that already exists as a file?)
