Displaying container statistics by using the CLI

An alternate method for viewing container statistics is by using the QoreStor CLI command: stats --container --name <container name>

This command shows the following information:

Container Name			:<name of the container>
Container ID			:<ID associated with container>
Total Inodes			:<total number of data structures in container>
Read Throughput		:<read throughput rate in Mebibytes or MiB/s for container>
Write Throughput		:<write throughput rate in MiB/s for container>
Current Files			:<current number of files in container>
Current Files Stubbed		:<current number of stubbed files in container>
Current Bytes			:<current number of ingested bytes in container>
Cleaner Status			:<current space reclamation process status for selected container>
Current Recycle Bin Files	:<when enabled, current number of files in Recycle Bin>
Current Recycle Bin Logical Bytes :<when enabled, current number of logical bytes in Recycle Bin>
Current Immutable Files	:<current number of files for which immutability is set, RDA containers only>
Current Immutable Logical Bytes:<current number of immutable logical Bytes>

For more information on QoreStor CLI commands, see the QoreStor System Command Line Reference Guide.

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 Cloud tiering 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:
    • If you have more than one Cloud Tier, select the required Cloud Tier that you wish to use for this container from the dropdown.
    • 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.
    • Enable Cloud Locking - If Cloud locking is enabled for this Cloud Tier, the container can use Cloud Locking. Based on the cloud provider being used there are different options. For AWS and other S3-Comptaible cloud providers (except Google Cloud), either of the two locking types can be chosen - Compliance mode, Governance mode. For Azure, the lock type is internally set.

    NOTE: Cloud Locking is currently applicable for RDA and Object container types. For the RDA container, the objects in the cloud are locked for the same immutability period as set on the backup images by the backup application. The locking mode is as per the user choice. For the Object container, the period and mode are both as set on the backup images by the backup application.

    • Click 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.
    • Stub Exclude Dir/Extensions/Regular Expressions (Optional) lets you exclude stubs based on their directory, extension, or regular expression. Refer to Using regular expressions for more information.
      • Stub Exclude Directory List. Excludes all stubs in the specified directory.
      • Stub Exclude File Extension List. Excludes all stubs with the specified file extension.
      • Stub Exclude File Regular Expression. Excludes only stubs 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.

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 Cloud tiering for more information.

Archive tiering is available for RDA and VTL container types.

To add an archive tiering policy

  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 Policyallows 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 archive migration. Specifies the number of hours files must be idle before being archived.
    • On-Prem Retention Age. Specifies the number of hours files will be kept locally after they are archived.
  4. Enable Cloud locking : If Cloud locking is enabled for this Archive Tier, the container can use Cloud Locking. Either of the two locking types can be chosen - Compliance mode or Governance mode.
  5. Click Advanced Options to view the following:
    • Folder Paths lets you to select files to 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.
    • Stub Exclude Dir/Extensions/Regular Expressions (Optional) lets you exclude stubs based on their directory, extension, or regular expression. Refer to Using regular expressions for more information.
      • Stub Exclude Directory List. Excludes all stubs in the specified directory.
      • Stub Exclude File Extension List. Excludes all stubs with the specified file extension.
      • Stub Exclude File Regular Expression. Excludes only stubs matching the entered regular expression.
  6. Click Enable.
