BackupAssist v4 and later

Description

A problem occurred when launching the backup.

There is one known situation where this occurs. If this article does not describe your problem, please contact our technical support (support [at] backupassist.com).

The Windows API Error 1816, Not Enough Quota, occurs because BackupAssist cannot assign the rights needed to log into the machine to perform the backup.

This occurs when there are other applications that have filled up the desktop window's Access Control Entries list. This situation is very rare, but we have noticed that it occurs more frequently on Terminal Servers.

Resolution

Check that your Backup User Identity has been set and has the required access. To view your current Backup User Identity, select the Settings tab > Backup User Identity and you'll see the following dialogue box appear.

Backup User Identity

Note: For BackupAssist 10.4.2 and earlier, the Backup User Identity is used for all backup jobs and the account may have been created with custom access levels. For 10.4.3 and later, a Backup User Identity is only required for Jobs that have a NAS destination or the SQL add-on, and in these cases, the Backup User Identity should be a member of the Administrators group.

What to check

  • For BackupAssist 10.4.2 or earlier - check that the account is still selected, enabled and has the required access.
  • For BackupAssist 10.4.3 and later, check that the account is still selected, enabled and a member of the administrators group.
  • To check the permissions properly, you can log into the backup server using the Backup User Identity account and check that you can read and write to the backup destination without any authentication requests or errors.
  • If backup account's password is changed in Windows, it will need to be changed in BackupAssist.
