Log Shipping Copy Job Fails once in a while
This is not SQL-Server error actually,

This occurs when the LS Copy Job tries to copy the file on destination location(On Shared Network location)
Now, when the location is not available due to temporary connection loss with network, or due to any reason. (when its connected through internet &amp; VPN reasons can be multiple)

So this can be broadly concluded as Network path was not reachable(not available at that time)

Solution: Check that if network location available before copy. If network location reachable then only Init copy.

I hope this answers what you are looking for.
