One license of SpaceObServer covers one installation. SpaceObServer can scan mutiple local, network and cloud paths. So, you can install SpaceObServer on one machine to observe multiple volumes. Because of the performance and the workload of this machine and the size and update intervals of the scanned paths it may be neceesary to have more than one instance running. If you are using SpaceObServer in a clustered environment, you need one license per node you install SpaceObServer on. For the correct usage of SpaceObServer on a clustered environment see this FAQ entry.

The performance of SpaceObServer is influenced most by these factors:

• Latency of the connection to the storage
• Performance of the SQL server
• The total number of file and folders
• Frequency of the scans (daily, weekly, monthly)

The minimum operating system for SpaceObServer is Windows 10, Windows Server 2016, or higher. We recommend at least 4 cores, 8GB of RAM and 200MB of disk space for the SpaceObServer installation.

SpaceObServer requires an SQL Server to store its data, we support Microsoft SQL Server 2012 or higher in all editions, Microsoft SQL Azure, MySQL 8.0 or higher and Firebird 3.0 or higher. In case you install the SQL server on the same machine as SpaceObServer, the system requirements for this machine increase by 24GB RAM, 4 cores and a minimum 4GB of disk space, the database size depends on the size and settings of the scans.

You always need a SpaceObServer (Enterprise or DataCentral) license as base. This license includes the SpaceObServer user interface for reporting and the SpaceObServer scan service which executes the scans and archives the file system information into a database.

The SpaceObServer Remote Client only includes the SpaceObServer user interface only, without the scan service. You can install SpaceObServer Remote Client on additional machines in your network to generate reports for scanned directory trees, by accessing the data stored in the backend database. You can also use the SpaceObServer Remote Client for remote administration of scans.

Each instance/installation of SpaceObServer Remote Client need to be covered by one SpaceObServer Remote Client license.

Please find more detailed information how to use SpaceObServer in your environment here.

Some database providers may not be installed on a device.

Please visit the following Microsoft page to download the SQL Server Native Client: Download Microsoft® SQL Server® 2012 Native Client - Latest Servicing Release from Official Microsoft Download Center

Please run the downloaded installer and try to connect to the database again.

This error is caused by an operation that is part of the deduplication process and tries to consolidate the different permissions of the duplicates.

Hardlinks all share the same permission settings, so the deduplication process tries to ensure that access rights that a user previously had will still apply after a deduplication.

Here's an example:
Assuming you deduplicate two duplicates "file A" and "file B".
File A has "read only" access for user X
File B has "read and write" access for user X
File B will be replaced by a hardlink that points to File A
The "larger" set of access rights from File B has to be applied to File A as well

In summary: When one of the files is replaced with a hard link to the other, the process will try to merge the permissions of the underlying data. In the example above, the consolidated access rights would be “read and write” for user x. 

However, this operation is only successful, if the current user is allowed to change access rights for that particular file, or for files in the current folder. It is important to keep in mind that having the access right to change or write a file does not automatically include the access right to change the permission settings of that file.

If you receive an error message "Failed to merge permissions: Access is denied", then this means your current user is not allowed to change these permission settings and no deduplication will be performed for this set of duplicates. 

This can be the case either if he does not have a "Allow" entry for the operation "Change permissions", or if an explicit "Deny" entry exists for that. It is also important to note that a “Deny” entry will always overrule a "Allowed" entry, if both are set.

There can be several possible causes:

• The last indexing run took place before the file was created or modified, so the current content of that file isn’t yet in the index.
• The indexing service may not have had sufficient permissions to access the file.
• The file’s type isn’t (yet) supported - see https://knowledgebase.jam-software.com/7719
• The file is invalid, corrupted or otherwise unreadable.
• DataCentral ran into a problem when extracting the file (for example, because it’s too large or has an unexpected structure).
• DataCentral does not index files that have any of these attributes: Hidden, Temporary, NotContentIndexed
• If the file was indexed successfully, but UltraSearch still doesn’t find your search term, it might be due to the term itself - or it could be that less important content (for example, HTML tag names) isn’t included in the index.

No, DataCentral does not transfer any sensitive data out of your company network. All data is stored in an on-premises database on your premises.

No cloud services are required or used when using DataCentral.

DataCentral has access control implemented.

Although, there might be files indexed that are not accessible by some users, DataCentral automatically only delivers search results the specific UltraSearch user has access to.

No. There are no limits regarding amount of files/data that can be indexed as far as we know.

When dealing with very large folders/drives, the infrastructure DataCentral is hosted on could cause performance bottlenecks, which could for example slow down the search in the index.

Usually, you need 1 license to run SpaceObServer and DataCentral on a server + n licenses of UltraSearch Professional for n people that can search the DataCentral indexes.

The amount of data in the indexes and the number of searches is unlimited.
