Considerations before you start using a Backup Operators group account

There are some items that you need to consider before you use a Backup Operators group account to back up, archive, restore, or retrieve your data.

Consider these items before using a Backup Operators group account to back up, archive, restore, or retrieve your data:

• If you have already been using the Tivoli® Storage Manager backup-archive client with an Administrators group account you might not be able to launch the client because you cannot open the log files (for example dsmerror.log). To alleviate this problem, you can grant the Backup Operators group Read and Write permissions to the log files or the directories containing these log files.
• If you have been creating system state backups with an account that is a member of the Administrators group, and if you want to start backing up or restoring data with an account that is a member of the Backup Operators group, you must delete the staging directory, c:\adsm.sys, before backing up or restoring the system state as a member of the Backup Operators group.
• If you have existing backups from a Tivoli Storage Manager Version 5.2 or earlier client and you attempt an incremental backup of an existing file space with a member of the Backup Operators group, all of the data appears as changed and it is resent to the Tivoli Storage Manager Server.
• Members of the Backup Operators group might not be able to back up or restore file data that was encrypted by an Administrator account using the Windows encrypting file system (EFS).
• Members of the Backup Operators group do not have the proper authority to update the last access time for files that is encrypted with the Windows encrypting file system (EFS). If EFS files are restored by a member of the Backup Operators group, the last access time will not be preserved.
