EC2 Instance Backup


Enable EC2 Instance Backup


Sign in to your CloudAware account. Go to Admin → Backup. To set up a global backup policy, go to the "Settings" tab and select the account. 
























To enable scheduled backups, select the time backups will start on from the list in 'Start at'.


Note

A backup task will back up all non-terminated instances, including instances in a ‘stopped’ state.


You can also select any instance from the list under the 'EC2 instances' tab and set the backup policy for it. This will override the global backup policy set on the account.


Dosable EC2 Instance Backup


To disable scheduled backups for EC2 Instance, select the instance under question and click ''Remove Policy'':





Note

Existing backups will be stored until they expire according to the backup policy rules. If an instance is terminated, backups are stored as well until they expire.



Backup Metadata


AMI Description will contain the following information about the original instance from which a backup is taken:

  • Instance ID

  • Key

  • Security Group(s)

  • Instance Type

  • Availability Zone

  • Public IP Address

In addition AMI will contain 2 backups tags:

  • Instance ID

  • Policy Type


Cost allocation tags can be applied to AMIs as well. Contact support@cloudaware.com for additional details.


View EC2 Instance Backup Status


By looking at any instance in CloudAware, we can tell what backup policies are in effect and check their status.


The following fields mark the backup policy and the backup status:

  • Daily Backups (the number of daily snapshots specified by the policy)

  • Daily Backups Status (the actual number of available consecutive AMIs starting from today's date)


    Tip

    For example, today is the 10th day of a month and Daily Backups field has value of 7 but Daily Backup Status has value of 3. It means that CloudAware only found backups for the last 3 days and the backups for the other 4 days that should be there are not present. Whenever the backup policy does not equal the backup policy’s status, a backup is missing


  • Weekly Backups

  • Weekly Backups Status

  • Monthly Backups

  • Monthly Backups Status


In order to view EC2 Instance backups, navigate to an instance of choice.Scroll down until you see a related list called EC2 Instance Backups.


Backup Tags


EC2 backup functionality relies on AWS tags to advise the backup scheduled task on how an instance should be backed up.

  • AWS backup tag name is: gig-backup

  • AWS backup tag value is: Nd-Nw-Nm, where N is number of days/weeks/months

Tip

For example, a backup policy 3d-10w-12m creates daily backups every day and rotates them over the period of 3 days, a weekly backup which will be rotated over 10 weeks and a monthly backup which will be rotated over 12 months. Hyphens can be omitted.


Examples of valid backup tag values:


Tip

1. 3d-10w-12m
2. 4d10w12m
3. 3d-10w
4. 3d
5. 3


3 and 4 are equivalent due to backwards compatibility.


Enable Orphaned Backup Retention


The Orphaned Backup Retention allows to manage an AMI clearing process. When setting up the global backup policy, insert the number of days in the 'Orphaned Retention (Days)' field. For example, Orphaned Retention = 10 means that backups will be deleted 10 days after the source instance is terminated:
