Veeam for Microsoft 365 “Download request retry timeout exceeded” error

/

Recently we have begun seeing the “Failed to backup item: FILEPATH, Download request retry timeout exceeded” error appear in jobs backing up OneDrive. Recent changes on the Microsoft side have begun preventing OneNote notebooks from being able to be downloaded. This prevents Veeam from being able to request and download the file to backup. We have an active case open with Veeam while they work with Microsoft to resolve this issue. We will update this post once Veeam and Microsoft have provided a public workaround or hotfix. Information on the issue can also be found here in KB4529. For additional assistance, please reach out to Support@Managecast.com.

Veeam Replication Latest Available Restore Point is Already Replicated

/

The replication warning “Latest available restore point is already replicated” appears when the replication job that’s sourced from a backup/backup copy attempts to run, but there is no new restore point to grab new data from. Here are a few reasons that may cause new data not to be available to replicate: These are some of the most common reasons we find that cause the “already replicated’ warning to occur. Veeam, replication, and virtualization are complex, so there are many reasons this may occur.

Veeam Agent for Windows “Sending e-mail report Details: The remote certificate is invalid according to the validation procedure”

/

When a certificate change to the SMTP server that your Veeam agent uses to send out notifications occurs, the notifications may start failing to send. Your jobs will begin displaying the warning message, “Sending e-mail report Details: The remote certificate is invalid according to the validation procedure.” This can be easily resolved by running through the email notification settings and testing that it can connect. 2. In the Configure and test email notifications window, verify and test your SMTP email settings. Selecting Test Now will test the current settings. 3. If the Test Now fails, you may need to make a change to warrant Veeam to rescan the certificate. Veeam will only rescan the certificate if a change has been made here. Clicking the Mail server drop down, switch it to one of the other options, then switch back is a significant enough to warrant a rescan. Click Apply to initiate the rescan. 4. You should be met with an alert stating that the certificates are mismatched. Continue through the certificate window. Run the Test Now option to verify Veeam can now connect. There may be other reasons that could be interrupting the communication between your Veeam Backup Agent for Windows and the SMTP server.

Veeam Explorer for Microsoft Exchange Timeouts

/

A possible issue when restoring a large number of items with the Veeam Explorer for Microsoft Exchange can be operations timing out. Especially when using the advanced search feature in large mailboxes. Error messages related to these timeouts can pop-up during the restore with the following message: Connection to server was unexepectedly close. See log file for details. Error: This request operation sent to net.tcp://127.0.0.1:59148/ArchiverExchangeServiceOrg did not receive a reply within the configured timeout (00:01:00). The time allotted to this operation may have been a portion of a longer timeout. This may be because the service is still processing the operation or because the service was unable to send a reply message. Please consider increasing the operation timeout (by casting the channel/proxy to IContextChannel and setting the OperationTimeout property) and ensure that the service is able to connect to the client. In the Veeam Explorer for Exchange log files (C:\ProgramData\Veeam\Backup\ExchangeExplorer\Logs) these errors may also be present: Error: The message could not be transferred within the allotted timeout of 00:01:00. There was no space available in the reliable channel’s transfer window. The time allotted to this operation may have been a portion of a longer timeout. Error: Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall. Error: A blocking operation was interrupted by a call to WSACancelBlockingCall To resolve this issue, the timeout can be increased by editing the Exchange Explorer config.xml file. To do this, follow these steps: Make sure that the Exchange explorer is closed and no restore sessions are running. If you are performing the restore from a Veeam for Microsoft 365 server, make sure no jobs are running and stop the Veeam Services: Next, open a text editor and edit the file: C:\ProgramData\Veeam\Backup\ExchangeExplorer\Config.xml Add the following text between the tags in the file: <WCF OperationTimeout=”3600″ />. Don’t modify any other lines in this file. Example: Finally, save the file and start the Veeam for Microsoft 365 services again. After following these steps try the restore again. The time-out issues should now be resolved.
