I cannot perform backups in Mamut
article ID: 2024445
The Backup procedure in Mamut Business Software version 12 is different from previous versions.
There are a number of possible situations that may occur with failed backups. Here is a list of the most common issues:
- Backup fails when upgrading with error 1098
- Backup when exiting Mamut fails
- MDatatools cannot find or access the SQL Server
- Backup fails cannot access the path \\server\ .... \ <filename>
- Backup fails cannot write to temporary shared folder
- Mdatatools will not start with an error message from Windows
Here are some of the causes and the solution:
In Mamut version 12 backups are performed by our backup program Mdatatools. This program can be stopped by the firewall when it is started directly by Mamut and therefore must have full access to the network and the SQL server.
The solution is to adjust the firewall on your computer and give both Mamut.exe and Mdatatools.exe full access to the network and the Internet.
Antivirus can also block Mamut from accessing Mdatatools. It is important to update the virus definitions in your antivirus software frequently and also ensure you have the latest version of Mamut has been installed.
If your antivirus program blocks Mamut from making a backup, the solution is to either exclude Mamut.exe, Mdatatools.exe and Idatatool.dll from all scans or by excluding the Mamut installation folder and sub-folders from scans.
You should also check that the antivirus programme has not quarantined any of Mamut's files. If this has happened the files must be restored from within the antivirus program. If this is not possible Mamut must be reinstalled.
File access in Mamut's document directory
When a normal backup is taken the database, documents and images are included. If the files are inaccessible or locked by other users, the backup will fail.
The solution is to ensure everyone has full access to the files.
Permission to create files in Mamut's document directory
Part of Mamut's backup process is performed by the SQL service on the server, when the user accesses the SQL server they will use their Windows username. The user creating the backup must have full access to Mamut's document directory. Therefore, all users should have full permissions to the document directory.
The path to the document directory can be found in Mamut by going into View - Settings - Other Settings - Other applications. When creating a backup from a client machine your system will use a local folder in your user profile in Windows. It is common that the backup function will complete on the server even if it fails from a workstation.
The path to Mamut's document directory is set up with a network drive
It is common to use mapped network drives for easier access to shared folders on the network. This will stop the Mamut backup when the SQL service on the server is running with their own username and it does not have access to these network drives. The path to the document directory can be found in Mamut by going into View - Settings - Other Settings - Other applications.
In a multi-user solution is recommended to use a UNC path (eg. \\Server\Public Mamut\Data\System000X).
When creating a backup from a client machine your system will use a local folder in your user profile in Windows. It is common that the backup function will complete on the server even if it fails from a workstation.
. NET on the machine is damaged
Mdatatools is written in and uses .NET Framework 2.0. If the .Net installation on your computer is damaged, it must be reinstalled. To remove .Net you must uninstall the version with the highest number first, then second highest number, and so on. When you have uninstalled, you must reinstall Mamut, this will automatically reinstall. NET 2.0.
If all else fails
You can export error log from Mdatatools. Select File - Database Utilities - Go to the systems Program folder. Select double click the Datatools folder and start the program Mdatatools.exe.
Login with a super user username and password, and go to the tab Log. Click the button on the left Export error log. Then send this log file to Mamut Support Centre.
