Issue:

After upgrading Avamar Server to version 19.10, backups and restores are failing with "Invalid Password" messages similar to the following:

2016-04-18 14:12:07 avtar Error <5180>: Failed to retrieve backup list from account '/Test/testclient' (error code 69 MSG_ERR_PSWD_INVALID).
2016-04-18 14:12:07 avtar Error <5181>: Did you specify the account (--acnt) correctly?
2016-04-18 14:12:07 avtar Error <5184>: No matching backups found.

Or

2016-04-18 12:13:21 avtar Error <8608>: Failed to complete backup; Authentication failure  (Invalid password?  User disabled?). (MSG_CMD_ACCESS_CHILD=47 serial=55 seq=0 flags=RU:N:0 kind=2 rsp=MSG_ERR_PSWD_INVALID retries=0)
2016-04-18 12:13:21 avtar Error <15085>: Backup not completed properly on server.

Cause:

This issue arises from cipher incompatibility between Avamar Server 19.10 and Client 19.8 when custom passwords are set for backuponly, restoreonly, and backuprestore accounts. Per the Avamar 19.10 Best Practices Guide (page 13), all passwords should be changed except for the backuponly, restoreonly, and backuprestore accounts.

In the current situation, these accounts are not set to the default password. This password must be set in both the mcserver.xml file and the Avamar server database. The procedure to complete this task is detailed below.

Procedure:

Install GoAV:
  1. For detailed information about this support tool, see article Avamar: GoAV tool on the Avamar server
  2. Ensure that the GoAV tool is at least at version 1.81 (though the latest version is recommended).
  3. Run the following GoAV Command to validate and fix account credentials:
./goav security fix-backup-account

Example Output:

Benefits of Using GoAV:

  • Synchronizes account credentials with the updated standards
  • Ensures that credentials remain valid even after applying hotfixes or upgrading the Avamar Server
  • This eliminates the need for any manual intervention

Contact Support:
If unable to resolve with GoAV or installation is not permitted, contact Dell Support and reference this article 000223208 for assistance with the issue.
