I have a case where DataMiner was set to take a daily full backup without database, but now issues are encountered when the backup is used (specifically unzipping the backup).
The logging information shows that the backup was completed successfully.
Is there any check that can be done to validate the backup, to check if no data was corrupted?
Thank you for the help.
The logging should provide full details on the creation of the backup file.
There are however some "manual" checks you can still do to be certain everything is fine e.g. when you want to use a backup file and you potentially missed the notice that something was wrong with the backup file.
When changing the .dmbackup file to .zip you can open the archive file and look at the content. In the update.zip it will include all the data form your DataMiner and you can search for specific data such as the database data or element files, etc
-> don't forget to change the extension back afterwards
Some use cases that I've seen in the past that could explain this behavior is a copy of our backup files to a network share but using another tool besides DataMiner (otherwise there would be a notice/error in the logging as well).Taking a backup file and copying it manually somewhere could also lead to corruption if it was aborted too soon. Sometimes Windows already created the package but some content is still missing.
A quick check to see if everything is still fine should be the size of the package.
