How to

Once the S3 Cubbit endpoint is configured, the backup job can be created:

  • Select the newly created S3 endpoint (S3-Cubbit) from the list.
  • Bucket name: select a previously created bucket or click on new bucket to create a new bucket immediately.
  • Multipart Size: you can leave the default value at 128 MB.
  • Then, click on Select.

The value of 128 MB refers to the single part that makes up the multipart upload. Setting this value to 128 MB will theoretically allow uploading up to 1.28 TB maximum size per single file since the maximum number of parts that make up a multipart upload is 10,000. Increase this value if you plan to upload single files larger than 1.28 TB in size.
