Limitations for Archive Tier

The archive tier has the following limitations:

  • Each type of repository that can be added as an archive extent is compatible only with corresponding type of repository configured as a capacity extent:
  1. To add Amazon S3 Glacier as an archive extent, select Amazon S3 repository in the capacity tier settings. If you do not have an Amazon S3 repository as a capacity extent of your scale-out backup repository, you must first configure it.
  2. To add Microsoft Azure Archive storage as an archive extent, select Microsoft Azure Blob repository in the capacity tier settings. If you do not have a Microsoft Azure Blob repository as a capacity extent of your scale-out backup repository, you must first configure it.

For more information on configuring capacity extents, see Add Capacity Tier.

  • Migrating data to another archive tier is not supported.
  • You cannot transport backup files from performance tier directly to the archive tier. Transportation to the archive tier is available only from the capacity tier.
  • Microsoft Azure Archive storage does not support immutability.
  • Imported backups cannot be offloaded to archive tier.
  • Incremental backup files cannot be stored in the archive tier.
  • Archive Tier does not support Azure accounts with the following redundancy options: zone-redundant storage (ZRS), geo-redundant storage (GZRS) and read-access geo-zone-redundant storage (RA-GZRS) accounts. For more information, see Microsoft Docs.
