I have a brand-new DS213, with up-to-date firmware.
In about 12 hours, My 2011 MacBook Pro has completed about 4GB of 550GB of a Time Machine backup.
At this rate, it will take over two months (68 days) to finish. The same backup on an attached external drive (via FireWire) took about 1 day.
To run this backup, I have the MacBook wired to my LAN via a Gigabit connection, with WiFi disabled.
It doesn't seem to be more than marginally faster than it did running over WiFi.
The DS213 has a very good reputation, and I doubt that Synology would advertise Time Machine compatibility if it were always this bad; I'm figuring that there's an option somewhere that will make this run significantly faster.
How do I make this work properly?
Thanks in advance
Josh

Re: Time Machine backup is s-l-o-w
Did you ever get this resolved?
I just installed a 213j and after 24 hours it's still waiting for its first backup in Time Machine, and I keep getting notifications that the backup failed. I have a 2014 MacBook Pro but the backup is s-l-ow like you said. Or it's not working right.

Re: Time Machine backup is s-l-o-w
I have a ds213j. I have been using it for time machine backups for a couple of years with no issues. Suddenly, in the fall of 2015 backups slowed to a crawl. I have tried just about everything I can find in apple and synology forums to try to fix it.
Most recently I've isolated the diskstation from my router, running it directly to my macbook through an gigabit ethernet switch and there is no change. I ran wireshark on the connection and found malformed afp packet errors which is the best clue I can find.
At one point, through some juggling, I mounted the backup volume over SMB and the backup went at a normal speed. This allowed the backup to complete and catch up, but when I moved it back to AFP, even though the backup jobs were smaller, it still crawled, taking hours or days to copy a couple of gigabytes.
Basically my diskstation has been a paperweight since late 2015. It could be a result of upgrading to el capitan, or maybe some bug introduced in the synology DSM software. I have not yet contacted Synology but that is my next step.

Re: Time Machine backup is s-l-o-w
I must assume you're all running on El Capitan.
The issue is not that of Synology, but that of El Capitan. I've come across the same situation and I've been astonished of the solution. I am running DSM 6.0 and thought that was the culprit. You can fiddle around with SMB2 with Large MTU support, SMB1 and SMB3 settings in File Services (Under Windows), but it doesn't solve the underlying issue of slow Time Machine backups.
You'll find the entire solution here:
http://apple.stackexchange.com/questions/212537/time-machine-ridiculously-slow-after-el-capitan-upgrade
For me, this sped up Time Machine backup from "calculating estimated time after already backing up 2,6 GB after 6 hours (!!) to doing a complete backup of my Mac Pro drive (489GB) in useful 13 hours.
Stop Time Machine before trying the code, start Time Machine and see what it gives for you. I've done the daemon script. This has been a very interesting experience.

Part of the issue is that low priority input/output-operations (I/O) now seems to get throttled heavily. You can check it via Terminal (can be found via Spotlight ⌘Space and entering terminal) then entering at the bash prompt:Code: Select all
fs_usage backupd
and look for the THROTTLED entries. If you see them, the backup is throttled.
So if you have a ton of files, just the time it takes to do the I/O takes forever, even if the files are small (because it performs a bunch more I/O operations around xattrs etc. than it used to).
Go to a Terminal and enter:Code: Select all
sudo sysctl debug.lowpri_throttle_enabled=0

It's also a good idea to re-enable the throttling after your backup finished successfully with the following commandCode: Select all
sudo sysctl debug.lowpri_throttle_enabled=1
