Some useful functionalities of Backup in Web UI are not available in the XML API. Like configuring Password or Scheduled Backup. Those operations are at server level.

I think it would be useful to add the 4 following operations :

backup-manager / set-secure-backup-settings
backup-manager / get-secure-backup-settings

With attributes like :
- use-password-protection : boolean
- password : string

backup-manager / set-schedule-settings
backup-manager / get-schedule-settings

With attributes like :
- enable : boolean
- period : 86400 | 604800 |2592000
- hour : integer from 0 to 23
- minute : 0 | 15 | 30 |45
- use-incremental : boolean
- full-backup-period : 604800 | 2592000 | 31536000
- max-dump-files-unit : integer
- backup-content-mail : boolean
- backup-content-vhost : boolean
- repository : local | remote
- failure-notification : boolean
- failure-notification-email : string
- suspend : boolean

It can also be done by adding more attributes to existing operations.
For password, on xxx-remote-storage-settings.
For Scheduled Backup, on backup-server.

Hey guys,

I am sure that I speak for hundreds of users when I say that having a limit on backups per customers and or subscriptions should be an important and available option. The option to also limit backups based on the customers subscription storage size will be even better. Otherwise, customers who overuse the backup option will dramatically increase storage space on the server without realization of the administrator. It wouldn't be ideal for an administrator to enter the dumps folder to delete random customer backups. Really hope you guys can resolve this and add this feature as soon as possible.

This may also be a security issue.
Currently there are no special protection of user content in the backup. Plesk protects only its sensitive data, web content archived without any encryption.

If some gains ADMIN access to a wordpress/drupal/other web applications install parts of the Plesk container file system, cron jobs, etc will be compromised and would undoubtably increase exponentially the chances of the system to be exploited with virus, rootkits, malware “indirectly” affecting Plesk. (as an analogy no point to build a metal wall if the door is still glass)

So, in other words ... if a wordpress installation is compromised the installations of malicious (or not) plugins can lead to the installations of rootkit, malware and virus at the container. I cannot see for a second how this would be good for any Virtuozzo container running Plesk and how you could consider Plesk not being affect if for instance the container is used to conduct a DDOS to a random host.

It would be great to have a single interface to manage backups of individual accounts (single-domain or single user).
I would like to manage a single server backup ftp and let me choose which accounts to backup.

Obviously the backup file must be "single" for each account and not a single file for the entire server. If you want to make the restore of a single account, I have to use a single backup file.

Currently I have a script that through bash (or cygwin for windows) backs up the single account by bees and upload via ftp on external storage. I would avoid using external tools and remain in plesk.
