Backup of a Dynatrace Managed Cluster with more than 1 node requires shared directory mounted at all nodes of the cluster at the same directory (NFS is recommended). Is the backup process resilient to outages of the mounted remote filesystem? For example - if the NFS server is non-reponsive - can this affect the normal Dynatrace cluster node operation? (of course, backups cannot be done during the outage) Are there any options for disabling the backup temporary? (for maintenance on NFS server) except for turning the backup on/off in the CMC? ---

Hi Julius, backup is triggered every 1 hour for elasticsearch snapshot from the database. In case of NFS unavilability, this operation will time out and not affect normal operation of the server or any other components. Backup is also triggered every 24 hours for cassandra dump. This is implemented as a separate script launched on each node. And again, if NFS is unavailable script will just fail to execute, or will run very long until times out. There’s no option to pause the backup. Frankly, it’s not so needed, as in worst scenario you will miss cassandra daily dump, but the previous backup should still be available. ---

Hello [@Július L.](https://answers.dynatrace.com/users/16467/view.html) and [@Radoslaw S.](https://answers.dynatrace.com/users/5499/view.html) I am a little confused regarding the storage path. Do we need to provide the physical storage path (e.g. 10.10.10.10:/dynatrace-ns/dynatrace-bkt) or the mounting point (e.g. /cluster\_configuration\_backup) created on all cluster nodes)? ![28234-1613052394999.png](https://global.discourse-cdn.com/dynatrace/original/3X/a/b/ab837c477694c55e866e9a383630cfc959029ce9.png) Regards, Babar ---

This should be the mounting point that was created across all cluster nodes for example /usr/local/dynatrace. ---

[@Malik R.](https://answers.dynatrace.com/users/9924/view.html) is correct. We had done the same thing. But Dynatrace might still list it as incorrect but the backup will still perform as expected ---

Hello [@Malik R.](https://answers.dynatrace.com/users/9924/view.html) and [@Chad T.](https://answers.dynatrace.com/users/36422/view.html) Thank you for your comments. It means I am going to use the mount point e.g. /cluster\_configuration\_backup Correct? Regards, Babar ---

Correct. It just needs to be the same mount point across all nodes. ---

[@Babar Q.](https://answers.dynatrace.com/users/5357/view.html) That’s correct. Dynatrace might say that it dosent like it, but it should still work. Or at least thats what it did back when we set it up as managed 2 years ago. ---

Yes, that is exactly what you will need to do. As [@Július L.](https://answers.dynatrace.com/users/16467/view.html) mentioned it needs to be the same mount point across all nodes. [Back up and restore a cluster](https://docs.dynatrace.com/managed/shortlink/managed-cluster-restore) example dynatrace used "On each target node, mount the backup storage to, for example, `/mnt/backup`. This path is referred to as `` " ---

Hey [@Radoslaw S.](https://answers.dynatrace.com/users/5499/view.html) this was back at my previous employer where we were a managed instance. For some strange reason Dynatrace would always have yellow under text from the mount point location. I dont quite recall what it stated, but the CMC didnt really like the mount point but never the less back backed up every night right on time. I can always reach back out to my contacts over there to see if the issue is still present, maybe get you a screen capture of it. ---

[@Babar Q.](https://answers.dynatrace.com/users/5357/view.html) are you using CIFS by a chance? ```auto Such problems may be caused by the caching in CIFS - that is why we recommend using NFS and not CIFS. The issue happens less often when "peristenthandles" and "actimeo=0" params are used when CIFS is mounted. ``` ---
