Temporary Folder Size for Agentless Microsoft 365 and Cloud File Backups

All agentless Microsoft 365 and Cloud File backup sets use a temporary directory location on the user home for backup and restore.

Each agentless Cloud File backup job requires at least 100 MB of free space for the temporary files generated during the backup job.

For each agentless Microsoft 365 backup job, the required free space for the temporary files generated during the backup job depends on two factors:

  • the number of Microsoft 365 users selected in each backup set, the required free space is calculated as 300 MB per Microsoft 365 user.
  • the number of concurrent Microsoft 365 backup jobs running on the AhsayCBS server.

Example

  • If an AhsayCBS server has only one backup set with 500 Microsoft 365 users, it will require 150 GB (500 x 300 MB) disk space on the user home drive for the temporary files generated during the backup job.

  • If there are multiple Microsoft 365 backup sets running concurrently on AhsayCBS, then the free space required will be the sum of all the Microsoft 365 users. If they are located on the same user home drive then the temporary folder on that drive will require 540 GB of free space for the temporary files generated during the backup job.

    Backup set 1 with 200 Microsoft 365 users (200 x 300 MB) = 60 GB

    Backup set 2 with 100 Microsoft 365 users (100 x 300 MB) = 30 GB

    Backup set 3 with 500 Microsoft 365 users (500 x 300 MB) = 150 GB

    Backup set 4 with 1000 Microsoft 365 users (1000 x 300 MB) = 300 GB

The default temporary directory is located at C:\\Program Files\AhsayCBS\user\ %username%\temp (the default path of the user home).

Ensure that the drive where the temporary directory is located has a lot of free space to accommodate all the agentless Microsoft 365 and Cloud File backup jobs, especially if they will be running concurrently.
