We add value to NetApp™ environments

Cleondris is developing NetApp add-on software since 2010 and has been a registered global technical alliance partner of NetApp since 2011. Our software extends the functionality of NetApp ONTAP, AltaVault and HCI installations. The set of add-on functionalities and the broad support for NetApp ONTAP versions is absolutely unrivaled amongst third party vendors. Our additional integrations with other products such as VMware™ vSphere and vCloud Director help NetApp customers get the most out of their NetApp installations.

Our Products

Cleondris™ Data Manager (CDM®)

Cleondris Data Manager (established in 2010) is the first backup, restore and indexing product explicitly developed for NetApp™ ONTAP & Cloud storage. Our optional integration for VMware™ environments can orchestrate array based backup & replication and scales from a few up to tens of thousands of virtual machines using a single instance of our software.

SnapGuard™ (SGEE)

SnapGuard (established in 2016) provides you with peace of mind by protecting your data fabric from malicious accesses. SnapGuard has been designed specifically to integrate into NetApp ONTAP storage systems (the enterprise edition features the world's first combined FPolicy and EVTX monitoring) and is therefore the ideal software for corporations already running on or planning to run on NetApp.

HCI Control Center (HCC)

HCC (established in 2018) is our brand-new add-on product for customers running NetApp™ HCI environments. The product offers storage failover for Element OS with VMware™ integration and soon will be able to orchestrate backups (intra-HCI, to ONTAP and to cloud/S3). Stay tuned!


We are the technology leader in the NetApp add-on field.

With many of the innovative features of our software we were the first on the market - and the story goes on and on!

Selected features brought to you first by Cleondris:

Restoring Virtual Machines from SnapMirror/SnapVault

The first version of Cleondris Data Manager was released in 2010, when we were the first to support automatic recovery of virtual machines from SnapVault backups. Cleondris was also the only vendor on the market where the restore of virtual machines on NetApp storage could be outsourced to the help desk staff using a web interface - without having to grant them any direct access rights to the NetApp or VMware toolchain. When NetApp introduced the new Clustered Data ONTAP (then called "C-Mode") in 2011, Cleondris was again the first company to offer restores from SnapMirror DP targets (XDP was not yet available, but we implemented it as soon as it was accessible), of course for both NFS and VMFS datastores. Currently, we are extending the underlying technology with support for NetApp HCI and backups in the cloud.

Single File Restore for Linux Guests

The dynamic LVM (Linux Volume Manager) re-signing technology developed by Cleondris in 2015 is unique on the market. We have integrated an independent (built from scratch) LVM-2 implementation into our software, which works without the help of agents or support of a Linux guest operating system. This allows the mounting of backups of virtual disks to running virtual machines - due to the automatic re-signing of MBR/GPT, LVM-2 (PV, VG, LV) and EXT-2/3/4 structures, the disks are easily recognized by the Linux kernel and there are no conflicts with active disks.

Scheduling Backups - a graphical Approach

If you are a storage administrator, then probably you feel like us: defining and understanding cron schedules for backup jobs is a tedious exercise - the cron format is just too cryptic. At Cleondris we find that managing and enforcing correct backup schedules is an important task. That's why we designed back in 2013 the world's first graphical HTML5 web-based backup scheduler for ONTAP snapshots and SnapMirror replications. Planning hourly, daily and weekly snapshots has never been easier, even if the schedule varies between days of the week. And if you need advanced features like backups on the last friday of a month, then Cleondris is of course able to do that.

NetApp Browser for Storage Admins

If you've been in IT for a long time, you'll remember Norton Commander. We were inspired by this legendary product and developed in 2013 the world's first web-based File Explorer for NetApp Data ONTAP. Not only can you easily browse, copy and restore data between volumes, SVMs or different clusters with NDMP - it allows you also to easily follow SnapMirror replication chains. It can even show you all different Snapshot versions of a file, even across XDP/DP replication cascades. In combination with our NetApp file search and support for FlexPool and cloud backups, this is a very powerful tool.

Indexing: Searching for Files

Storage administrators spend a lot of their time helping their users find and recover lost data. Cleondris supports storage admins with the first file system meta-data indexing & search solution optimized exclusively for Data ONTAP (in use by customers since 2017). Developed from the ground up, it integrates optimally with NetApp snapshots, NDMP, SnapDiff, and SnapMirror features. A single Cleondris installation scales from small business environments up to systems with billions of files, and can be added to existing setups in minutes. Unlike other solutions on the market, we also do not rely on general-purpose third-party open-source indexing packages: our underlying multi-versioning database technology used for indexing is based on the latest scientific research results in the field, is optimized for use with NetApp SnapDiff and has been developed by Cleondris in Switzerland.

Using FPolicy to detect and defeat Ransomware

NetApp's FPolicy framework has existed for a long time. However, NetApp has only made it available to selected partners so that they can implement HSM and quota management solutions, among other things. Cleondris is the first company that came up with the idea to implement active ransomware detection and automatic defense with FPolicy in 2016. But Cleondris is not resting: since 2018 we also have an integration into the NetApp file service audit log facility (EVTX files), which in combination with FPolicy provides new exciting possibilities.

Differential Restore for unstructured Data

There are countless solutions on the market that promise protection against ransomware. That no solution can offer 100% protection is obvious and to promise anything else would be dishonest. Cleondris therefore goes one step further: in 2016 we invented the differential restore for Data ONTAP, which automates NetApp SnapDiff, NDMP and SIS (Single-File-Clones). With this technology you can automatically restore the necessary parts of a snapshot backup into the active file system and recover destroyed data. Unlike a full restore (e.g., a volume-level SnapRestore), the files not affected by ransomware will not be touched and stay in their newest version, even if they have changed since the latest backup.

Web-based EVTX Viewer for Data ONTAP

You are probably aware of this situation: your security officer urgently needs access to the NetApp file service audit logs, but for security reasons they are not accessible via CIFS and therefore the storage administrator has to copy them into another security zone first and important time is lost. But that's not all: although the files are in the general EVTX format, the security officer cannot simply evaluate them because the data fields are NetApp specific. We have the solution: with our brand-new and exclusive RBAC/Kerberos integrated EVTX explorer you can give your security officers exclusive 24/7 web-based access to EVTX files. With our filtering options they always have the needed information at their finger tips and compliance issues can be handled promptly.
