Synology NAS, Long Backup/Small File

Thread needs solution

I have a Synology NAS 4T network station, and I have been trying to back up one of the computers on my network for weeks. Starting with ATI 2013 and now 2014, for a full backup it says (haven't been able to complete) that the backup will take 2 days plus, and I believe it. Found it running this morning after I would estimate 24h from start, with an estimate of 2 days, 16 hours and some minutes to complete, and increasing. I cancelled and deleted all backups, and tried just to run a file backup of the single hard drive, (about 200G of data), and it ran for about 15 seconds and showed a backup file size when completed of about 1K, which I'm guessing doesn't include all of the files no matter how good the compression (which was set on normal). The other 3 computers on my home network back up fine, although they did take 2-4 hours for the initial full backup (using Version Chain scheme).

I have tried every conceivable configuration of ATI backup with the offending computer, optimized the disk, checked for errors, turned network protection and antivirus program (Norton 360) on and off; no difference. It backed up fine with ShadowProtect when I used that (of which all vestiges have been erased), and I even got it to back up the system once with v2013 ATI (took about 4 or 5 days), with a file of about 300G on the NAS. It seems to want to run every subsequent backup as a full backup as well, and if I turned on the schedule the computer wouldn't be doing anything but backing up full time, which sort of defeats the purpose. Computer is an HP all-in-one touch screen, which seems to be operating fine. Win 7 Home Premium, 64-bit. Plenty of room on the NAS, which is also operating optimally.

I'm stuck; any assistance appreciated!

Doc.H,

What model is your Synology and is it using the latest firmware?

There have in the past been problems with some Synology models with specific firmware. How are you accessing the NAS, via a mapped drive or IP/UNC ?

Does your NAS model also have a USB connection? If it does, it would be an idea to see if the same problem exists when accessing the NAS by that method as well. It may also be an idea trying to FTP into the NAS if it allows that sort of access.

Is the NAS connected via a router, if so, have you tried a direct network connection?

If you happen to have a spare USB connected drive, does that exhibit the same problem? Just trying to see where the congestion problem might lie.

Have you tried installing and running Wireshark and seeing if that shows excessive dropped packets or transmit retries?

I would also suggest running chkdsk /r (the /r is important) on both the souce drive and the NAS, just to make sure that TI hasn't found a disk sector problem which other software couldn't care about.

NAS is on my wireless network through a router, to which the NAS is connected directly, Linksys EA6500. Synology DS213 with a pair of 2T drives, working fine; DSM v4.3-3776. I have run checkdisk repair, more than once, and no errors. Have not connected via USB (geography of the house would require moving it, inconveniently). The NAS does allow FTP, but I've never been able to find the drive using my boot recovery disk, no matter how I configure it, and the Acronis menu is far from intuitive. Direct USB connection to a piggyback Seagate worked fine previously just to copy files, but I haven't used ATI with it, since my goal was a universal backup solution on one device for all four of my networked home computers. I'm honestly thinking of hooking up an NAS independently and directly, since it appears Acronis does not play well with networks, at least mine.

It might be the wireless part that is the problem. I suppose temporarily hard wiring the NAS is out of the question?

Does your NAS have a fixed IP? I'm wondering if you enter a fixed IP when making the recovery media, this might solve the drive not being seen, it won't solve the throughput problem I wouldn't have thought, but might allow the drive to be visible.
