Backup SQL

Thread needs solution

Hello,

I have a problem with SQL database backup. The backup ends with a VSS error. However, there is no VSS error when the VM Server backup on which SQL is running. I attach a message in the attachment
 

Can you help me please?

Hi,

The error occurs on SQL databases validation stage where invalid paths to databases are detected (double slash in path affects consistency of VSS snapshot). Quote from the log + there are also other similar entries for other DBs:

Hello,

how can I exclude one SQL backup when I back up VM and all SQL databases on this server? There is a possibility to back up files that meet the criteria, but I do not know what to enter there.

For example, I would like to exclude this database from VM backup:

"Preparing to backup applications" has been successful, but with these warnings: '

Database Name: SUSDB

Database logical file name: SUSDB_log

Incorrect value: f: \ WSUS \\ UpdateServicesDbFiles \ SUSDB_log.ldf

 

Thank you in advance

Milan

Hi Milan,

When performing application-aware backup of VM, it's not possible to exclude applications data partially (separate SQL DBs for example) from processing. This is possible only if you install Agent for SQL inside the VM and back up the SQL DBs separately - after the agent installation, the SQL server instances and DBs can be drilled down from "Devices"->"Microsoft SQL" section in web console.

Therefore in your case you can for example perform VM backup without enabling application protection and set up "Files filters" option (Backup Options->Files filters) to exclude SQL DB files from processing (in order to avoid double space consumption in backup storage). In addition to this backup plan, set up separate backup plan for SQL DBs which will be performed by Agent for SQL running inside the guest OS.

Alternatively you can fix the paths to SQL DBs as mentioned in my previous comment - in this case there will be no warnings even during application-aware processing of VM backup.

Thank you.
