Adding a Cloud Tiering policy

Once a cloud tier is created, you must enable a cloud tiering policy for a container before that container can be replicated to the cloud. Refer to Adding a Cloud Tier for more information.

  1. In the navigation menu, click Containers. The Containers page is displayed.
  2. In the list of containers, find the correct container and then click Enable Cloud Tiering Policy.
  3. In the Enable Cloud Tiering Policy page, enter the following information:
    • Cloud Policy-- allows you to configure the amount of time that files must be idle before being sent to the cloud as well as how long to keep a local copy of the files. The configured times should be less than the backup expiry or retention time configured in the backup application. When the backup is expired by the backup application, the files corresponding to the backup are removed from local storage and cloud storage.
      • Idle time before cloud migration--Specify the number of hours files must be idle before being sent to the cloud.
      • On-Prem Retention Age--Specify the number of hours files will be kept locally after they are sent to the cloud.

    Click on Advanced Options to view the following:

    NOTE: The Advanced Options settings are not supported for object containers.

    • Folder Paths--files can be included or excluded based on their location.
      • Include--only files in the listed directories will be included for replication.
      • Exclude-- all files except those in the listed directories will be replicated.
    • File Extensions/Regular Expressions--files can be included or excluded based on their extension or by regular expressions. Refer to Using regular expressions for more information.
      • Include--only files with the specified extensions will be included for replication.
      • Exclude--all files except those with the specified extensions will be replicated.
      • Include Regular Expression-- includes only files matching the entered regular expression.
      • Exclude Regular Expression-- excludes only files matching the entered regular expression.
  4. Click Enable.

NOTE: To add a cloud tiering policy through the command line, use the command container --cloud_policy

Refer to the QoreStor Command Line Reference Guide for more information.

Using regular expressions

QoreStor provides an option to select files for inclusion (or exclusion) based file names, character sets, and extensions using regular expressions.

Example expressions

  • To include all the files with filename starting with “BackupImage” and having extention .tar, .gz, or .zip.

    ^Backupimage.*.(zip|tar|gz)

  • To perform a simple match of backup images with IMG | HDR | META

    (IMG|HDR|META)

  • Support for complex regex patterns using character class , meta sequence, and range
    • To match files with filenames starting with [abn] and having file extention .txt, or.log

      ^[abn]\S*. (txt|log)

    • To match file names with only alphanumeric characters. For example, the expression below matches test1 , f123file etc.,

      [[:alnum:]]+

    • Archive series of log files. For example, the expression below matches the first five logs of ocafsd & aws logs

      ocafsd[1-5].log|aws[1-5].log

Limitations

The current implementation of regular expressions does not support the use of global modifiers such as /g or /i.

In order to perform case-insensitive matching, a combination of character classes may be used. For example, the expression below can be used to find all combinations of quest, QUEST, QuESt , QUesT, etc.

[Qq][Uu][Ee][Ss][Tt]

Adding an Archive Tiering Policy

Once an archive tier is created, you must enable an archive tiering policy for a container before that container can be archived to the cloud. Refer to Adding a Cloud Tier for more information.

 

Archive tiering is available for RDA, VTL, and Object container types.

  1. In the navigation menu, click Containers. The Containers page is displayed.
  2. On the Containers pane, find the container you wish to archive. Click the ellipses icon, and click Enable Archive Tiering Policy.
  3. In the Enable Archive Tiering Policy page, enter the following information:
    • Archive Policy-- allows you to configure the amount of time that files must be idle before being sent to the cloud as well as how long to keep a local copy of the files.
      • Idle time before arcfhive migration--Specify the number of hours files must be idle before being archived.
      • On-Prem Retention Age--Specify the number of hours files will be kept locally after they are archived.

    Click on Advanced Options to view the following:

    • Folder Paths--files can be included or excluded based on their location.
      • Include--only files in the listed directories will be included for replication.
      • Exclude-- all files except those in the listed directories will be replicated.
    • File Extensions/Regular Expressions--files can be included or excluded based on their extension or by regular expressions. Refer to Using regular expressions for more information.
      • Include--only files with the specified extensions will be included for replication.
      • Exclude--all files except those with the specified extensions will be replicated.
      • Include Regular Expression-- includes only files matching the entered regular expression.
      • Exclude Regular Expression-- excludes only files matching the entered regular expression.
