Does the bwCloud provide a backup option?[faq_backup_1]

No. The services offered in bwCloud focus on providing infrastructure to run virtual machines. The users themselves are responsible for maintaining their data, backups included - both their images and their user data.

Does the bwCloud offer a special interface for a backup / data protection?[faq_backup_2]

No, we do not offer a special interface. However, the data of the (running) instances can be backed up with conventional on-board mechanisms like software clients or scheduled data copy operations.

How can I backup my virtual machines now?[faq_backup_3]

Snapshots of instances and attached volumes can be created via the dashboard. Snapshots of instances are images and can be downloaded with the CLI clients (openstack-client) (keyword: openstack image download ...). Images can also be created from volumes (keyword: create image from volume) and downloaded in the same way. For large volumes it is easier and more efficient to export data directly from the instances, e.g. with rsync, scp or similar tools.
