- Open Windows Explorer, right-click a local drive, from the context menu select Configure Shadow Copies.
- Set an appropriate limit large enough to allow shadow copies to be created. Typically 15-20% of the volume is needed to create shadow copies.
How to increase the shadow storage area
No backup logs OR Exchange error “XXXX isn’t assigned to any management roles”
Error
During an exchange backup, the backup starts and immediately finishes with no backup logs being created.
OR the following error is seen:
[XXXX][error] [OBM.ErrorStream] com.ahsay.afc.microsoft.MSExchangeExpt: [listPublicFolderDatabases] Processing data from remote server failed with the following error message: The user “DOMAIN.local/Computers/VMEXCHANGE” isn’t assigned to any management roles. For more information, see the about_Remote_Troubleshooting Help topic.
Cause
The user defined in “Domain authentication for Windows” is not part of the “Organization Management” security group and so the backup cannot start
Resolution
- Edit the domain authentication for windows item in the agent config
- Enter credentials for a valid administrator user that is a member of the “Active Directory Users and Computers -> Microsoft Exchange Security Groups -> Organization Management” security group
- OR simply add an existing user to this security group and update the domain authentication details in the agent config.

[ERROR] VSS_E_INSUFFICIENT_STORAGE
Error
[ERROR] VSS_E_INSUFFICIENT_STORAGE
Cause
There is not enough storage available to complete the snapshot.
Resolution
- Check the free space on all the volumes that have backup sources in the backup configuration. VSS requires a bare minimum of 320MB free space to function properly.
- Check & increase the amount of storage assigned to shadow copies via either
LogonUserW Logon failure: the user has not been granted the requested logon type at this computer
Error
[XXX][error] [CM-SBS Exchange BackupSet (1417735865455)]
[XXX] Error uploading data. Reason = ‘[WindowsUtil:createProcessAsUserN] Failed to LogonUserW for wcDomain=’DOMAIN’ username=’cmadmin’. (1385) Logon failure: the user has not been granted the requested logon type at this computer.
Cause
The user defined in “domain authentication for windows” does not have appropriate access privileges (either local or group policy) needed to start the backup.
Resolution
- Check the credentials defined in the “windows domain authentication” settings
- Check local and group policies to ensure that the user has administrator privileges
- As a last resort – set the “Log On” settings for the backup scheduler system service to logon as a valid user, rather than the “Local System” account.

Best practices for file backup agents
The advice provided here is for basic/entry level environments. For larger/more complex data sets, we recommend you contact us to discuss a tailored backup solution built from the ground-up to handle your storage and retention requirements.
| Item | Recommendation |
|---|---|
| OS volume | The file backup agents are file data backup tools and are not designed to backup the operating system. Only capture data files. For operating system backup, contact CyberSecure for a solution designed to backup the entire OS. |
| Don’t backup the root of volume or drive letter, eg selecting the top-level C:\ or D:\ | This will include hidden and system files that are stored in the root of a volume. Any files saved to this location in future will be added to the backup. Best to backup the specific folders you need |
| Structured databases | SQL or Exchange databases are structured data and require their own backup set. Use a separate specific backup set type to capture these. Exclude them from the file backup set to avoid duplicating data. |
| Number of files in backup set | For performance and reliability keep the number of files in each backup set ideally below 500,000 (and definitely below 1 million).
If the restore process is interrupted it cannot resume, so having a larger backup set means a slower restore time if the transfer needs to resume. Restores cannot happen in parallel within the same backup set, so again it’s critical that each backup set is kept as small and agile as possible, with a restoration in mind. |
| Large files |
|
| Backup set organisation | Design the backup sets with restoration in mind: split data logically up into priorities, eg: for smaller sets: “Data (current)”, “Data (archive)” For larger sets, split by department, eg: “Accounts (current)”, “Accounts (archive)”.If data is really disorganized then local changes may be required first. We cannot stress enough how important it is to keep the backup sets as small as possible and organised with restoration in mind. |
| Delta merging | In general, leave delta merging switched off |
Universal unique identifier not found
Error
Universal unique identifier (UUID) was not found
Cause
Signature changed on disk
Resolution
- Edit backup job
- Re-select volume(s) to backup

E-mail Account Quota exceeded. Unable to add “XXXX”
Error
E-mail Account Quota exceeded! Unable to add “XXXX”
Cause
This error is caused by an insufficient number of mail-level licences for the CyberSecure backup service account.
If the entire Exchange store has been selected, then every mailbox in the store will be backed up, which could mean mailboxes created after the backup was initially setup.
Resolution
More Exchange mail-level licences are required to be purchased under the account: equal to or greater than the number of mailboxes attempting to be protected.
To backup only specific mailboxes, simply select the individual mailboxes in the backup configuration, rather than the entire store.
Generic log error messages are shown in capitals
Error
Log entries similar to the following are shown (these may also appear in the client user interface):
1 Info xxxx BS_ACB_START
2 Info xxxx BS_GENERAL_MSG
3 Info xxxx BS_GENERAL_MSG_WITH_SYMBOL
4 Info xxxx SC_SNAPSHOT_CREATED
5 Info xxxx SC_SNAPSHOT_DELETE
Cause
This can be caused by an auto-upgrade not completing properly.
Resolution
Please reinstall or upgrade the software from the original installer.
Duplicate log entries and backup failures
Issue
When backups run duplicate entries are observed in the details log files in addition to errors such as:
1 Info 2015/04/09 18:34 Start [ Linux 3.2.0-4-amd64 (fserver), CyberSecure Advanced 6.23.0.0 ]
2 Info 2015/04/09 18:34 Start [ Linux 3.2.0-4-amd64 (fserver), CyberSecure Advanced 6.23.0.0 ]
3 Info 2015/04/09 18:34 Using Temporary Directory /tmp
4 Info 2015/04/09 18:34 Using Temporary Directory /tmp
and the following errors later in the backup:
Another backup job is still running. Backup skipped.
Unable to do Offsite backup, Error=[Bptree.KeyRangeIterator.hasNext] Error=[BufferedRandomAccessFile][EOFException] /tmp/BackupSet/1394080712673…
Cause
This issue is caused by a corrupted local backup profile.
Resolution
Perform a local profile reset

How to set a fixed profile location
- Find an existing valid local profile (.obm) folder
- Stop the online backup scheduler service
- Copy this folder into c:\cybersecure so it looks like c:\cybersecure\.obm
- Replace home.txt to contain only the following single entry: c:\cybersecure\.obm
- Set home.txt to read-only
- Restart the online backup scheduler service
- Check the scheduler log to confirm the next scheduled backup date(s)
- Open the backup agent to confirm it can see the new profile location
