Dynamics restore from backups ruin Append Mode Synapse links.

If you have synapse link in Append mode (to keep history)

The following scenario has no reasonable options for keeping history.

1. a D365 backup is taken (versionNumber is up to 10)
2. a production release to D365 goes wrong (versionNumbers up to 20)
3. within the release window a restore to backup to point 1 is done.

When this occurs

1. the synapse link (the internal Dsf subscription) is removed
2. attempts to create the new link fail due to a non-empty target storage container.
3. you have to erase the existing container to re-establish the link.
4. when you re-establish the link, the next update has a versionNumber of 11, duplicating values which occurred after the backup was taken (11-20).

Step 2/3 means you can not preserve history though this scenario.

Step 4 means that after you restore from backup, anyone who has consumed the old data now has two copies of versionNumbers 11-20.

Feature request

1. some way to preserve history through a dynamics restore from backup
2. when d365 restores from backup, please do not reduce the versionNumber back to an older value but keep it continually increasing over time.
