Restoring backups - FSx for OpenZFS

Restoring backups

You can use an available backup to create a new file system, effectively restoring a point-in-time snapshot of another file system. You can restore a backup using the AWS Backup or Amazon FSx consoles, AWS CLI, or one of the AWS SDKs. For more information on using the AWS Backup console, see Restoring backups in AWS Backup

Restoring a backup to a new file system takes the same amount of time as creating a new file system. The data restored from the backup is lazy-loaded onto the file system, during which time you will experience slightly higher latency.

The following procedure guides you through how to restore a backup to a new file system using the Amazon FSx console.

To restore a file system from backup (Amazon FSx console)

  1. Open the Amazon FSx console at https://console.aws.amazon.com/fsx/.

  2. From the console dashboard, choose Backups from the left side navigation.

  3. Choose the backup that you want to restore from the Backups table, and then choose Restore backup. Doing so opens the file system creation wizard.

  4. For File system name - optional, you can enter a name using a maximum of 256 Unicode letters, white space, and numbers, plus these special characters: + - = . _ : /

  5. For Storage capacity, enter a value that is equal to or greater than the storage capacity of the original file of which the backup was taken, in GiB. The range of valid values is 64–524288 GiB.

  6. For Provisioned SSD IOPS, you have two options to provision the number of IOPS for your file system:

    • Choose Automatic (the default) if you want Amazon FSx to automatically provision 3 IOPS per GiB of SSD storage.

    • Choose User-provisioned if you want to specify the number of IOPS. You can provision a maximum of 160,000 SSD IOPS per file system for Single-AZ 1 (non-HA and HA) and a maximum of 400,000 SSD IOPS per file system for Single-AZ 2 (non-HA and HA) and Multi-AZ (HA)*. You pay for SSD IOPS that you provision that exceed 3 IOPS per GiB of SSD storage.

      Note

      *The maximum SSD IOPS you can provision for Multi-AZ file systems depends on the AWS Region your file system is located in. For more information, see Data access from disk.

  7. For Throughput capacity, you have two options to provide your desired throughput capacity in Megabytes per second (MB/s). Throughput capacity is the sustained speed at which the file server that hosts your file system can serve data.

    • Choose Recommended throughput capacity (the default) if you want Amazon FSx to automatically choose the throughput capacity. The recommended value is based on the amount of storage capacity that you chose.

    • Choose Specify throughput capacity if you want to specify the throughput capacity value, and choose a value of 64, 128, 256, 512, 1024, 2048, 3072, or 4096 MB/s. You pay for additional throughput capacity that you provision above the recommended amount.

    You can increase the amount of throughput capacity as needed at any time after you create the file system. For more information, see Modifying throughput capacity.

  8. In the Network & security section, provide networking and security group information:

    • For Virtual Private Cloud (VPC), choose the Amazon VPC that you want to associate with your file system.

    • For VPC Security Groups, the ID for the default security group for your VPC should be already added.

    • For Subnet, choose any value from the list of available subnets.

  9. In the Encryption section, for Encryption key, choose the AWS Key Management Service (AWS KMS) encryption key that protects your file system's data at rest.

  10. In Root volume configuration, you can set the following options for the file system's root volume:

    • For Data compression type, choose the type of compression to use for your volume, either Zstandard, LZ4, or No compression. Zstandard compression provides more data compression and higher read throughput than LZ4 compression. LZ4 compression provides less compression and higher write throughput performance than Zstandard compression. For more information about the storage and performance benefits of the volume data compression options, see Data compression.

    • For Copy tags to snapshots, enable or disable the option to copy tags to the volume's snapshot.

    • For NFS exports, there is a default client configuration setting which you can modify or remove. Client configurations define which clients can access the volume and their permissions.

      To provide additional client configurations:

      1. In the Client addresses field, specify which clients can access the volume. Enter an asterisk (*) for any client, a specific IP address, or a CIDR range of IP addresses.

      2. In the NFS options field, enter a comma-delimited set of exports options. For example, enter rw to allow read and write permissions to the volume for the specified Client addresses.

      3. Choose Add client configuration.

      4. Repeat the procedure to add another client configuration.

      For more information, see NFS exports.

    • For Record size, choose whether to use the default suggested record size of 128 KiB, or to set a custom suggested record size for the volume. Generally, workloads that write in fixed small or large record sizes may benefit from setting a custom record size, like database workloads (small record size) or media streaming workloads (large record size). We recommend using the default setting for the majority of use cases. For more information about the record size setting, see Configurable volume properties.

    • For User and group quotas, you can set a storage quota for a user or group:

      1. For Quota type, choose USER or GROUP.

      2. For User or group ID, choose a number that is the ID of the user or group.

      3. For Usage quota, choose a number that is the storage quota of the user or group.

      4. Choose Add quota.

      5. Repeat the procedure to add a quota for another user or group.

  11. In Backup and maintenance - optional, you can set the following options:

    • For Daily automatic backup, choose Enabled for automatic daily backups. This option is enabled by default.

    • For Daily automatic backup window, set the time of the day in Coordinated Universal Time (UTC) that you want the daily automatic backup window to start. The window is 30 minutes starting from this specified time. This window can't overlap with the weekly maintenance backup window.

    • For Automatic backup retention period, set a period from 1–90 days that you want to retain automatic backups.

    • For Weekly maintenance window, you can set the time of the week that you want the maintenance window to start. Day 1 is Monday, 2 is Tuesday, and so on. The window is 30 minutes starting from this specified time. This window can't overlap with the daily automatic backup window.

  12. For Tags - optional, you can enter a key and value to add tags to your file system. A tag is a case-sensitive key-value pair that helps you manage, filter, and search for your file system.

    Choose Next.

  13. Review the file system configuration shown on the Create file system page. For your reference, note which file system settings you can modify after the file system is created.

  14. Choose Create file system.
