"No Disks have been mounted" error in Veeam while restoring guest files in Windows

While restoring guest files of Windows systems in Veeam (LFR restore), you may get the following error:

No Disks have been mounted. Either disks of this type aren't supported or some error occured. See log file for details.

This error might be connected to the Symantec Backup Exec installed on the same server as Veeam Backup & Replication. Also interesting, that this error occures only for LFR restore, other types of restore are not affected.

There are two possible solutions for this issue.

The number of active calls\channels in Asterisk - output to file

Sometimes it is necessary to determine whether there are enough channels of ground telephone lines, in case if the operator is connected to Asterisk. To collect such statistics in our company, we decided to record every minute (ideally, of course, more often) the number of active calls\channels in Asterisk to file, then plot if required.

There are two steps in the task:

  1. Output needed data to file in manual mode.
  2. Put the script into cron.

Find all snapshots in VmWare vSphere

It's no secret that when you perform backup with Veeam Backup & Replication, sometimes it "forgets" to delete the its snapshots. This leads to the fact that all virtual machine starts to work entirely on snapshot all the time. This is a costly operation, which significantly reduces the performance of the virtual machine.

In addition, system administrators can create snapshot manually and forget about it. We had a case in our company when a virtual server half-year (!!!!!) worked on the snapshot.

Fortunately, VmWare provides a plugin for Powershell, PowerCLI, which you can use to find all these snapshots.

Slow work of Veeam Backup & Replication GUI interface

The longer you work with Veeam Backup & Replication, the lower and lower its interface work. Apparently, this is because Veeam stores in database information about all sessions of the interface. Once they become so numerous that queries to the database begin to slow down.

So we need:

  1. Set up Veeam to not to store all this unneeded information.
  2. Delete existing data from database.
  3. Truncate and shrink database.

After performing these steps, my Veeam client started to work much faster.
