Q: Time machine synology broken after El Capitan upgrade

I recently upgraded my iMac 2014 retina to El Capitan and this has broken my previous time machine connection to my external Synology server (DS1513+).  I have been previously using this synology server with no problems with previous versions of OS X.  I have tried several workarounds on various forums including:

1. Rebuilding internet connection (deleting ethernet and then enabling again)

2. Selected AFP only vs. SMB only under file sharing in prefs menus (with all permutations).

3. Synology is up to date with latest software update.  Within Synology control panel, Mac File service is enabled with Time Machine pointing to the right folder. 

4. Ran disk utility on the time machine bundle file - no problems detected. 

 

I can access the server from my finder window but when I try to "Enter Time Machine" I get the "Can't Connect to a Time Machine Backup Disk. Also, I tried selecting and deselecting the backup disk from the list but still it's unable to correct.  Any help would be greatly appreciate!  Thank you!!!

    A third-party network-attached storage device (NAS) or router is unsuitable for use with Time Machine, especially if it's your only backup. I know this isn't what you want to hear. I know that Time Machine accepts the device as a backup destination. I know that the manufacturer says the device will work with Time Machine, and I also know that it usually seems to work. Except when you try to restore, and find that you can't.

    Apple has published a specification for network devices that work with Time Machine. No third-party vendor, as far as I know, meets that specification. They all use the incomplete, obsolete Netatalk implementation of Apple Filing Protocol.

    Apple does not endorse any third-party network device for use with Time Machine. See this support article.

    If you want network backup, use as the destination either an Apple Time Capsule or an external storage device connected to another Mac or to an 802.11ac AirPort base station. Only the 802.11ac base stations support Time Machine, not any older model.

    Otherwise, don't use Time Machine at all. There are other ways to back up, though none of them is anywhere near as efficient or as well integrated with OS X. I don't have a specific recommendation.

    If you're determined to keep using the device with Time Machine, your only recourse for any problems that result is to the manufacturer (which will blame Apple, or you, or anyone but itself.)
