Overview of Block Volume Backups
The backups feature of the Oracle Cloud Infrastructure Block Volume service lets you make a
point-in-time backup of data on a block volume. These backups can then be restored to new
volumes either immediately after a backup or at a later time that you choose.
Backups are encrypted and stored in Oracle Cloud Infrastructure Object Storage, and can be
restored as new volumes to any availability domain within the same region they are stored.
This capability provides you with a spare copy of a volume and gives you the ability to
successfully complete disaster recovery within the same region.
There are two ways you can initiate a backup, either by manually starting the backup, or by
assigning a policy which defines a set backup schedule.
Manual Backups
These are on-demand one-off backups that you can launch immediately by following the steps
described in Backing Up a Volume. When launching a manual backup, you can specify whether
an incremental or a full backup should be performed.
Policy-Based Backups
These are automated scheduled backups. Each backup policy has a set backup frequency and
retention period. There are three predefined policies, Bronze, Silver, and Gold.
The Oracle Cloud Infrastructure Block Volume service provides you with the capability to
perform volume backups automatically on a schedule and retain them based on the selected
backup policy. This allows you to adhere to your data compliance and regulatory
requirements.
Use Block Volume policy-based backups to perform automatic, scheduled backups and
retain them based on a backup policy. Consistently backing up your data allows you to
adhere to your data compliance and regulatory requirements.
Note:-
Deleting Block Volumes with Policy-Based Backups All policy-based backups will eventually expire, so if
you want to keep a volume backup indefinitely, you need to create a manual backup.
Volume Backup Policies
There are three predefined backup policies, Bronze, Silver, and Gold. Each backup policy has
a set backup frequency and retention period.
Bronze Policy
The bronze policy includes monthly incremental backups, run on the first day of the month.
These backups are retained for twelve months. This policy also includes a full backup, run
yearly on January 1st. Full backups are retained for five years.
Silver Policy
The silver policy includes weekly incremental backups that run on Sunday. These backups are
retained for four weeks. This policy also includes monthly incremental backups, run on the
first day of the month and are retained for twelve months. Also includes a full backup, run
yearly on January 1st. Full backups are retained for five years.
Gold Policy
The gold policy includes daily incremental backups. These backups are retained for seven
days. This policy also includes weekly incremental backups that run on Sunday and are
retained for four weeks. Also includes monthly incremental backups, run on the first day of
the month, retained for twelve months, and a full backup, run yearly on January 1st. Full
backups are retained for five years.
Note:- Backup Details
Backups are not an identical copy of the volume being backed up. For incremental backups, they are a record
of all the changes since the last backup. For full backups, they are a record of all the changes since the
volume was created. For example, in a scenario where you create a 16 TB block volume, modify 40 GB on the
volume, and then launch a full backup, upon completion the volume backup size is 40 GB.
Planning Your Backup
The primary use of backups is to support business continuity, disaster recovery, and longterm
archiving requirements. When determining a backup schedule, your backup plan and
goals should consider the following:
Frequency: How often you want to back up your data.
Recovery time: How long you can wait for a backup to be restored and accessible to
the applications that use it. The time for a backup to complete varies on several factors,
but it will generally take a few minutes or longer, depending on the size of the data
being backed up and the amount of data that has changed since your last backup.
Number of stored backups: How many backups you need to keep available and the
deletion schedule for those you no longer need. You can only create one backup at a
time, so if a backup is underway, it will need to complete before you can create another
one. For details about the number of backups you can store.
