General

Dear Forum Members,

I hope this message finds you well. I am contacting you to request your assistance regarding a problem we have been experiencing with our Orthanc system since 05.01.2026.

This is the third client whose image and database folders have been deleted without any apparent reason. We are concerned about the implications of this for our work and the integrity of our data.

If anyone has experienced similar problems or has any ideas on how to resolve this situation, I would greatly appreciate your contribution. Any help you can offer will be invaluable to us as we work to resolve this critical situation.

Thank you for your time and support.

Can you give more information about your Orthanc setup (Storage, Database, etc..) and detail the problem a little more.

/**

* back-end of Orthanc. You will have to install the
* “orthanc-postgresql” package to take advantage of this feature.
**/
“PostgreSQL” : {
// Enable the use of PostgreSQL to store the Orthanc index?
“EnableIndex” : false,

	// Enable the use of PostgreSQL to store the DICOM files?
	"EnableStorage" : false,

	// Option 1: Specify explicit authentication parameters
	"Host" : "localhost",
	"Port" : 5432,
	"Database" : "orthanc",
	"Username" : "postgres",
	"Password" : "postgres",

	// Option 2: Authenticate using PostgreSQL connection URI
	// "ConnectionUri" : "postgresql://orthanc_user:my_password@localhost:5432/orthanc_db",

	// Optional: Disable the locking of the PostgreSQL database

Do you got the time the files were deleted and possibly some logs of the period ? Also, how is the disk space in percent ? 40%, 60%, 80%, … full ?
