Using local licenses in Macrium Reflect to backup to NAS.  Backups working fine.  Using site manager to monitor backups and logs, but all backups are initiated by the end points. I'm seeing hundreds of zero length files on the NAS that start with "macrium_repoonline_test_{ " followed by about a 32 digit hex number .  The modification date of the files goes back over a month with time stamps ranging from a  minute to a few minutes apart.

Does anyone know what is creating these files and not removing them?  Is there a way to stop this behavior?

Hi Ken,

These files are created by the Site Manager's connection testing of the repository - as part of the periodic monitoring it checks that the repository is writable. The files it creates are created with a "delete on close" flag - so they should be automatically closed by the SMB server on the NAS. It might be that either the user for the repository has file create permissions but not file delete permissions, or that there's an unusual SMB server configuration that doesn't honor the flag. Either way, the files can be safely deleted.
I will also add a feature request to our system to add a manual delete of these files to the repository test, so that they get cleaned up if the mechanism we currently use fails.

Kind Regards,

Alex

As usual Alex, you hit the nail on the head.  Login for site manager had file creation but not deletion.  

The connection testing seems too frequent.   I'm getting access log entries at an average rate of of about one per minute from site manager, is there a way to reduce this interval? I assume these are being used to update the repository state after client backups, could these updates be triggered by log activity form the clients?

Hi Ken,
The status online checks for a repository happen at a default rate of once every 2 minutes - although this is automatically reduced if there are a lot of repositories. There is a registry key you can set on the Site Manager server to reduce these checks - this might help your issue:

Affects: Site Manager Server
Key: HKEY_LOCAL_MACHINE\SOFTWARE\Macrium\CMCAgent
Value: "RepositoryOnlineStatusMonitorFrequency"
Type: DWORD
Default: 120


the naming is a little odd as it's a key which has existed since Site Manager was Central Management Console in version 6!

Kind Regards,

Alex

Is this the same issue for Reflect Home edition?

I noticed that my external drives will no longer go into standby mode and spin down once I install Reflect Home edition.

Hi,

This issue affects the Site Manager server service only - it's unrelated to any Reflect issues
