It will prevent you from data loss and downtime if a single drive failure happens which is, by far, the most common/likely occurrence. If backups are not being done very frequently, or the volume is split across multiple physical enclosures, then perhaps SHR2 offers more emotional safety! smile.gif

What about the backup set on a DX510? Can this, and should it, be set to no redundancy (assuming it is only used for backups)?

You build it as a separate volume with whatever redundancy you like. For me, I actually just go with a JBOD (no redundancy). The chances of my primary data set getting corrupted and also having the offsite disks (I make backups and then remove them from the DX510) are extremely low.

I backed up the shares of my DS1512+ to my DX510. Was fast and worked fine. Now when I go to back up again I want it to be an incremental backup, which it does, but I would also like it to delete files from the DX510 which are no longer on the DS1512+. Is that possible with the default Backup & Restore app?

Not sure exactly what you mean. There is a backup option you can turn off that says "preserve destination files" you might have a look at that.

What I wanted to do was to keep the DX510 in sync with the DS1512+. So, if I delete a TV show on the 1512+ it would not continue to be stored on the 510. If you preserve destination files then I think those files can't be overwritten. That would be great for an initial backup of files you wanted to keep.

I don't think that the Synology backup utility will do what you are describing, but you might be able to simply use rsync to do that and set it up as a job that runs however often you like.

However, I would think it might be safer to do your backups to the DX510 volume periodically like once every week or two and take the volume offsite. When you do that backup you can just set the backup job so that the files on the destination volume are not preserved and it won't keep backups of files you have since deleted.

That's an excellent suggestion. Just to be on the safe side, do I have to shut down the DS1512+ to remove the disks from the DX510? Or can I just power down the 510 from its own power switch and then put in a new set of hard drives? I assume if I put the original set of drives back into the 510, the order doesn't matter?

Synology does not have a way of "ejecting" a volume (at least via the GUI), so what I normally do is shut down the Disk Station, then remove the drives/volume from the DX510 and then power back up. 90% of the time I don't even turn my DX510 on because my backup volume is not in it.

Order of disks may or may not matter depending on the type of volume, but in general I don't believe that it cares.

I have my 1512 for a few weeks now and everything has gone smoothly except when I accidentally pulled the plug on an external drive while copying blu ray folders to it. Quite a scare when everything froze up. All is well now.

About a year ago I switched from DSL to cable and love the increased speed. However I get frequent drops to the 1512 and other hardware (sat tv dvrs, ipods etc). The cable modem has a built in router. My question is what routers are you guys using with the synology? I have limited experience setting up a router and after reading all the reviews, I am completely clueless as what to buy.

Any help will be much appreciated. Thanks.

I don't know that this thread is the place for a large recommendation list of routers/switches... you might want to start a new thread. The Synology is just a device that needs a gigabit ethernet connection, the type of router/switch shouldn't be of particular concern as long as it supports gigabit ethernet.

Sorry I did not mean to cause a problem. I have read your entire thread a few times and thought that with your experience I would ask what you were using as I value your opinion. I did not want to hijack your thread and turn it into a router discussion. My apology.

You should create a thread describing your setup (all components) and what is not working and what the desired behavior is. There are plenty of people who can help you, I just don't want a very useful thread for Synology discussion taken off of the rails with a side topic.

Is anyone else seeing buffering problems after update to the latest DSM 4.1? My XBMC Win 7 started exhibiting problems buffering higher bitrate content after I updated to DSM 4.1, nothing else changed.

I increased XBMCs buffer size to 500MB and the problems seemed to disappear but it's disconcerting nonetheless. I am tempted to reload the XBMC machine but curious if anyone else had seen this behavior.
post #435 of 581
Since this seems to be primary Synology thread, I figured I would post in here to get some advice.

I originally had a HP 485, but moved onto a home built WHSv1 when I ran out of space. I currently run a WHS V1 with about 16TB. I have around 5TB in backups and another 4.5TB of video which I have duplicated. The WHS seems to be running fine, but my storage is getting low. I only have 300GB free. It doesn't seem to make sense to throw more money at the WHS v1 especially with the incompatibility of the newer drives.

I also have several TBs of data on home PCs I would want to move to the NAS. I just don't have the room on my WHS to do so now.

My thought is to pickup a DS1812 and move my video share to the Synology while still using the WHS for backups of the house PCs. It sounds like most are using synctoy to backup the Synology to their WHS. I would either use that or maybe try the free P2P with Crashplan while also backing up the Synology into the cloud.

Anyone see any problems with this setup? I realize as the Synology fills up it would surpass the free space of the WHS but I figure I can deal with that when I get to it.
post #436 of 581
I went from a HP EX490 to Synology 1812+. You'll find my posts some pages back. For the most part, no problems, but I did have a handful of movies and TV episodes that failed to copy. Ended up taking the drives out of my WHS setup and connecting via a 3.5" hard-drive dock connected to my desktop PC, then transferred over to 1812+.
post #437 of 581
Yeah I saw that. My plan would be to transition over time since I don't plan on buying all the drives at once. I figure I will pick drives up as deals pop up.
post #438 of 581
I keep reading that most still use their WHS for computer backups? Does Synology not do backups? I'm looking into making a switch to Synology and retiring my WHS v1 but it seems like I might need to keep it.
post #439 of 581
I opted for SHR-2, which uses a 2-drive failure scheme, so I don't back-up my entire 20TB+ of data. Instead I only back-up my home videos and photos.

I went from two WHS v1 units to a Synology 1512+ with the esata expansion unit. Best thing I have ever done. At first I kept the WHS systems and used sync toy as I had been using it between the 2 WHS computers. But I have since divested myself of WHS and use the built in Synology backup. It backs up my drives in the 1512 to the expansion drives on a weekly basis. It can also do network backups.

So, yes it does do backups. WHS is very neat and restoring a PC from a backup is trivial.Sync toy works well. In general, WHS is just a really good OS. I think a lot of people reluctantly gave up their systems after Microsoft sent out mixed signals and then completely switched directions. Am not a big Windows user but I really liked WHS. I was about to buy a WHS2011 system when MS seemed to pull the plug. Went to Synology and have been very happy. I haven't upgraded to DS4.1 until I see a bit more feedback. DS4.0 works great so there doesn't seem to be a reason to upgrade.

I don't know what sync tool people are using with Synology, but I have looked at a few that are supposed to support it. I am more than likely going to replace the WHS at my wife's office in the next year and will probably replace it with a Synology since I have had great success with the DS1511+ I have in the basement. I will however have to find a good backup client that will make full restores possible for the 8 or so XP and Win 7 computers at her practice.

That is a really strong point in favour of WHS. The backup and restore capabilities are great if you are using Windows' systems. I doubt there are many utilities for a NAS that can restore a complete system as well as WHS can. Fortunately when I moved to the Synology I also migrated away from Windows except for my XBMC nettop and so the backup issue wasn't there. I was mainly interested in how to best back up the NAS!

There are quite a few decent backup solutions out there for Windows clients, the problem is that they typically cost $40-$50 per client, which if backing up 10 or so machines gets pretty expensive.

It has been reported by Brajesh that you cannot add a SMALLER drive to a volume once it is created, new drives need to be equal to or larger than the smallest size drive in the array.

heh, forgive me delving into this thread, but I thought I'd just re-emphasise this point. I tired to be smart, buy 2x3tb drives to dump all my drives' content that had been in pc, and then use the drives to bump up the storage on my 1512+ (ie., 3/3/1.5/1/500gb)

Alas, once you've build the RAID with the 3tb, you're stuck, and need to replace with at least another 3tb.

If I would have started with the smaller drives copied to one of the 3tbs, then built the raid, then copied to the NAS from the 3tb, then added both drives into the NAS, I'd have been OK.

Still might do that at some point, but for now I'll just run it as two separate Volumes, not the end of the world, but annoying to say the least that it's not emblazoned in red on the Synology calculator page.

Another little thread update. I've been following the CES news to see if Synology was going to bring out the successor to the DS1812 (DS1813?) but from what I can tell that box won't be available for a little while yet.

I ended up running down to 1TB of space on my DS1511+ with 5X2TB drives so I went ahead and added two of the new Western Red (made for NAS) 3TB drives into my DX510 and it bumped the useable space all the way up to 11.5TB. Then, a week or so later one of my original Seagate 2TB drives started spitting out SMART errors so I went ahead and replaced that with another Red drive. Power consumption on the DX510 is really low... like 10-12 watts by itself. The whole stack right now with 7 bays populated and three red and four green drives is about 30-40 watts which is quite impressive. 1KW UPS should be able to hold the whole thing up for over 15 minutes during a brownout.

I've also found this handy storage calculator that might help others... you simply plop in number of disks and sizes you want and it will show you how much useable space you get using SHR vs traditional RAID as well as what products can handle that # of discs.

http://www.synology.com/support/RAID_calculator.php

Down the line I will probably still migrate all seven disks to some kind of eight bay enclosure from Synology, but at this point I think I'm going to hold out to see if they release one this time next year with redundant power supplies.

@jmpage2

For 11.5 TB of space I assume you are using the DX520 as part of the array? Do you allow the drives to hibernate? There is some setting mentioned by Synology about an automatic switch for the DX510 which seems tied in with sleep. I just connected the esata cable, plugged the DX510 in and turned things on. Are you familiar with some switch on the DX510 that needs to be set? I used to have the drives sleep after 30 minutes of non-use but that started causing delays with some media players. Any suggestions for power settings? I wonder if this is related to 4.1. I don't recall having these issues before.

There is no switch on the DX510, it will power up automatically when you power up the diskstation. It is completely slaved/controlled from the DS1511+. If you press the power button on the DX510 you can turn it off, but the DS will see that it is gone and turn it on again after a few minutes. Back when I only used the DX510 for making offsite backups I would actually pull the power cord from it so that it was completely offline from the DS. They are designed to work together.

Since my volume spans both the DX510 and DS, the DS would never put the DX to sleep... so I can't comment on that. Since I use surveillance station now for my CCTV recording the DS never completely hibernates, so can't comment on that.... what I can say is that the system is very power efficient considering the number of disks in use. For comparison purposes, when I was using my EX495 with four disks plus a five bay external enclosure, I had about 6TB of useable space and it was using close to 100 watts. The DS+DX510 with more storage space is using less than 50% of that.

I was hoping they would announce something. Amazon is currently out of stock of the 1512, 1812, and dx513. I was debating on buying the dx513 expansion bay, but I will have to wait for Amazon to restock.

From a post on Facebook a month or so ago, Synology had indicated they expected DS1513+ and DS1813+ to drop sometime in January, so it might only be a matter of a few weeks now. They might have simply opted not to show the new models at CES as they are likely similar to the predecessors and they don't want to kill sales of final inventory, which isn't exactly being sold at a discount.

I don't expect anything revolutionary, likely just lower power consumption and faster processors. I think I can hold out with my DS1511+ for another year to see if they have a more substantial upgrade up their sleeve for 2014.

Yeah I don't expect a huge change, but as I upgrade my 1812+ drives I am left with 1TB Reds not being used. As a result I was either going to pick up the expansion unit or a 5-8 bay unit possibly for offsite. I will just hold off for now until the new units come out. I only have two 1TB drives at this moment, but eventually I will be up to 5.
