Each volume has an indicator called **bootable** which shows whether an operating system can be booted from it or not. That indicator can be set up manually at any time. If you set it up on a volume that does not contain a bootable operating system and later try to boot a VM from it, you will see an error as a response.

Volumes created in the **Volumes > Volumes** section are *persistent* storage. They can be attached to a virtual machine and then reattached to a different one. They survive the removal of the virtual machine to which they are connected. You can also clone them, which is a simple way of creating a backup. However, if you copy them, you might also be interested in [Volume snapshot inheritance and its consequences on CloudFerro Cloud](Volume-snapshot-inheritance-and-its-consequences-on-CloudFerro-Cloud.html.md).

Those backups are stored using object storage. Restoring a backup will delete all data added to a volume after backup was created.

It is highly advisable to put no more than 1 million (1 000 000) objects into one bucket (container). Having more objects makes listing of them very inefficient. We suggest to create many buckets with a small amount of objects instead of a small amount of buckets with many objects.

S3 is a protocol for storing and retrieving data on and from remote servers. The user has their own S3 account and is identified by a pair of identifiers, which are called Access Key and Secret Key. These keys act as a username and password for your S3 account.
Usually, for desktop computers we refer to files within a directory. In S3 terminology, file is called “object” and its name is called “key”. The S3 term for directory (or folder) is “bucket”. To mount object storage in your Linux computer, you will use command **s3fs**.

To access data stored on a volume from another virtual machine, you need to disconnect that volume from virtual machine to which it is currently connected, and connect it to another instance.
