Understanding archives

The Rapid Recovery Core saves snapshot data to the repository. While a repository can reside on different storage technologies (such as SAN, DAS, or NAS), the most critical performance factor is speed. Repositories use short-term (fast and more expensive) media. To prevent a repository from filling up quickly, the Core enforces a retention policy, which over time rolls up recovery points and eventually replaces them with newer backup data.

If you need to retain recovery points, whether for historical significance, legal compliance, to fulfill offsite data storage policies, or other reasons, you can create an archive. An archive is a copy of recovery points from your repository for the specified machines over a date range that you designate. Archiving a set of recovery points does not delete the original recovery points in your repository. Instead, the archive freezes the collection of recovery points at the point in time in which the archive was created, as a separate copy in a storage location that you specify. Unlike recovery points in your repository, the data in an archive are not subject to rollup.

You can create, import, and attach archives from the [Archives] Archive option on the button bar, or from the Archives page accessible from the [Archive] 
    (More) icon on the Core Console.

Archive creation and storage options

You can create a one-time archive on demand at any time.

You can also define requirements for continual scheduled archive. This action creates an archive of recovery points for the machines you select, in the location you designate. Additional recovery points for those machines are then continually appended to the archive on a schedule you define (on a daily, weekly, or monthly basis).

When you create an archive, you specify where you want to save it. You can store an archive in a file system (locally or on a network), or in a storage account in the cloud.

NOTE: Before archiving to a cloud account, you must first add the credentials to the storage account on your Rapid Recovery Core. For more information about defining a cloud account in the Core, see Adding a cloud account.

If storing your archive in an Amazon cloud storage account, you must define the storage class when creating the account. To archive directly to Amazon Glacier, you can specify Glacier storage when defining the location in the Archive Wizard. For more information about Amazon storage classes, see Amazon storage options and archiving.

  • One-time archives are read-only. When creating a one-time archive, the destination location you specify must be empty.
  • When using scheduled archive, the Core appends additional recovery points to the existing archive.
  • If the storage medium you selected runs out of space, Rapid Recovery pauses the archive job, letting you specify another location. Your archive is then split into segments, which can reside in different locations, as space allows.

Amazon storage options and archiving

When archiving data in an Amazon Simple Storage Service (S3) account, you can choose from various storage classes. Each has different associated costs, benefits, and access restrictions. Prices may differ by region. Rapid Recovery release 6.2 extends support of Amazon storage accounts to all storage classes. This is useful when planning to store Rapid Recovery archives in the Amazon cloud.

Understanding storage classes available and the difference in lead times to access those classes is critical to control storage costs effectively while being able to access your archives within acceptable time frames.

NOTE: Quest provides this information as a courtesy to its Rapid Recovery customers to help raise awareness of storage pricing factors. These concepts can help you plan and budget accordingly. You are responsible for all storage costs on Amazon or for any other cloud service provider. Since Amazon can change prerequisites, requirements, costs, storage tier definitions, and so on, use the Amazon website as the primary and authoritative source for that information.

In general, Amazon currently offers the following storage classes.

Standard. This storage class is for data you plan to access frequently or access quickly. This class is the default storage option from all Rapid Recovery wizards, windows, and dialog boxes. There are no separate fee to retrieve information in the standard storage class.

Standard Infrequent Access (IA). This storage class is more economical than standard, intended for data that you do not intend to access frequently. There is a retrieval fee associated with accessing data in the storage class. However, availability is immediate. Amazon charges fees for objects deleted from Infrequent Access storage before 30 days.

Glacier. This storage class is for long-term storage of data that does not require real-time access. It is most economical for long-term storage of data that is rarely retrieved. There is a retrieval fee associated with accessing data in this storage class. Amazon charges fees for objects deleted from Glacier before 90 days. Retrieval of data stored in Glacier is not immediate. Standard retrieval times require 3 to 5 hours; bulk retrieval for large amounts of data can take up to 12 hours. Expedited retrievals can take up to 5 minutes. Fees apply to each retrieval option.

NOTE: Unlike the other Amazon storage classes, Rapid Recovery does not support the creation of a cloud account that is specific to Glacier. To archive data in Glacier, choose an Amazon cloud account, and select the Use Glacier storage option in the Location page of the Archive Wizard.

Reduced Redundancy Storage (RRS). This category is a lower-cost storage class is designed for noncritical reproducible data with less redundancy than the standard storage class. There is a minimal retrieval fee associated with accessing data in this storage class. A fractional percentage (Amazon cites as much as .01%) of objects stored in this class are expected to be unrecoverable.

For the most recent information, always review materials on Amazon's website.

In general, the following guidelines apply:

  • If you expect to restore data on any regular basis from a Rapid Recovery archive, Standard is likely to be the best option.
  • From a cost perspective, if you plan to restore data occasionally, consider Standard Infrequent Access.
  • Glacier is intended for cold storage of archived recovery points from which you rarely expect to restore. A good example of when to use Glacier storage is when saving data for regulatory compliance. Glacier is available as an archive option from the Archive Wizard.
  • For storage of noncritical, reproducible data, consider RRS.

Recovery point chain options for archives

Before creating your archive, you must decide on the proper approach for recovery point chains. Use the following information to determine which option you select in the Options page of the Archive Wizard.

  • Build complete recovery point chains, including referenced base images outside the date range. If you select the option to build complete recovery point chains, then you can perform the full range of restore actions for any recovery point in the archive. This range includes file-level restore, volume-level restore, and bare metal restore. When you select this option, full recovery point chains are saved with your archive. You can restore data even if the base image corresponding to the selected recovery point is earlier than the date range of your archive. However, the file size of this archive is larger, to ensure that you have access to data in the full recovery point chain.
  • Include only the recovery points in the date range. This saves space, but you are responsible for archiving any needed base images. If you include only the recovery points in the specified date range in your archive, the file size of the archive is smaller. For data in which the base image is included in the date range you specified, you have access to the full range of restore options. However, if you want to recover data captured in a base image from a date earlier than the date range you specified, you may be restricted to file-level recovery only. Data outside the range of the archive is orphaned.
