= Configuring the backup storage location with a MD5 checksum algorithm
|
|
|
|
[role="_abstract"]
|
|
You can configure the Backup Storage Location (BSL) in the Data Protection Application (DPA) to use a MD5 checksum algorithm for both Amazon Simple Storage Service (Amazon S3) and S3-compatible storage providers. The checksum algorithm calculates the checksum for uploading and downloading objects to Amazon S3. You can use one of the following options to set the `checksumAlgorithm` field in the `spec.backupLocations.velero.config.checksumAlgorithm` section of the DPA.
|
|
|
|
* `CRC32`
|
|
* `CRC32C`
|
|
* `SHA1`
|
|
* `SHA256`
|
|
|
|
You can also set the `checksumAlgorithm` field to an empty value to skip the MD5 checksum check. If you do not set a value for the `checksumAlgorithm` field, then the default value is set to `CRC32`.

|
|
.Prerequisites
|
|
|
|
* You have installed the {oadp-short} Operator.
|
|
* You have configured Amazon S3, or S3-compatible object storage as a backup location.
|
|
|
|
.Procedure
|
|
|
|
* Configure the BSL in the DPA as shown in the following example:

`checksumAlgorithm`:: Specifies the `checksumAlgorithm`. In this example, the `checksumAlgorithm` field is set to an empty value. You can select an option from the following list: `CRC32`, `CRC32C`, `SHA1`, `SHA256`.

[IMPORTANT]
|
|
====
|
|
If you are using Noobaa as the object storage provider, and you do not set the `spec.backupLocations.velero.config.checksumAlgorithm` field in the DPA, an empty value of `checksumAlgorithm` is added to the BSL configuration.
|
|
|
|
The empty value is only added for BSLs that are created using the DPA. This value is not added if you create the BSL by using any other method.
