I am attempting to use an *sshfs* mount for a Disk Safe. However, every time I try to create a Disk Safe, the CDP Server crashes. I cannot set permissions on the *sshfs* filesystem to anything other than a specific user / group.

Unfortunately, CDP does not support file systems based on FUSE: [http://www.r1soft.com/linux-cdp/cdp-30-enterprise-edition/requirements/].

The reason is that FUSE file systems do not support the *fsync()* call, which is critical to making a Disk Safe survive crashes, power losses, and other types of failures.
