Storage

Block storage volumes from 10 GB to 10 TB

A volume is block storage that exists independently of any server. Attach it to a server and use it like a disk; detach it and attach it to another server to move the data. Volumes range from 10 GB to 10 TB, can grow while they are in use, and are billed per GB per month.

Key features

  • Data that outlives servers

    Delete or rebuild a server and the volume, with your data, stays.

  • Grow online

    Increase the size while the volume is attached and in use, then grow the file system.

  • Mounted for you

    On servers from our Linux images, a new volume is formatted and mounted automatically, and added to fstab.

  • Move between servers

    Detach a volume and attach it to another server in the same location.

  • Stable device path

    Each attached volume has a stable device path that does not change between boots.

  • Pay per GB

    Billed per GB per month, by the hour, capped monthly like every resource.

What it is used for

  • Database data

    Keep the data directory on a volume so you can resize or replace the server without copying data.

  • Uploads and media

    Store user uploads and media on a volume that grows with your application.

  • Moving a workload

    Detach from an old server and attach to a new one to migrate in minutes.

Block storage: questions and answers

Clear answers about location, infrastructure and billing.

How large can a volume be?
From 10 GB to 10,240 GB (10 TB). Volumes can grow but never shrink.
Can I attach a volume to several servers?
No. A volume is attached to at most one server at a time. Detach it to attach it elsewhere.
Are volumes included in server backups?
No. Server snapshots and backups cover the server disk only. Back up volume data separately.
Do I have to format a new volume?
Not on servers created from our Linux images: a blank volume is formatted with ext4 and mounted automatically. On other images you set it up by hand.
