In Reply to: RE: To NAS or not to NAS posted by lokie on November 14, 2014 at 06:00:12
I have a NAS that I use to backup all my computers. The individual computers are responsible for backing themselves up to the NAS. (This is automated with O/S backup software for all the files except the music library. File synchronization software is used to backup the music library, so normally music files on the NAS remain unchanged, just new ones added as the library grows.)
Since the NAS is only being used for backups and since it is somewhat immune to hard drive failures due to a RAID 5, there is no need for frequent backups of the NAS. Instead, every so often I run file sync software between the NAS and external hard drive(s) that go into a Blac-X slot connected via ESATA. These hard drives normally reside off-site so as to be safe from fire, flood and theft. To minimize NAS power consumption, noise and hard drive wear and tear the NAS only runs when needed for backups. It turns itself on and off for scheduled backups and I can start and stop it manually for other backups. All the computers that have large files are connected via a gigabit Ethernet switch, so backup operations are fast.

What synch program do you use? I've used AllWaySynch for years but, though it was excellent in the past, I find increasingly that, as my library grows, it gets flakier and flakier and . . .
Just checked - my "fullest" HDD holds 80,000 files in 7,000 folders and about 1.6TB. That's not, I'd have thought, exceptionally large.
These days, I cannot run a full "synch" session without the system getting slower and slower then crashing. The only cure - and it's partial - is to reboot after each run. This is the case whether I synch locally or over a network except that, in the latter case, the source and target boxes both get sick.
A sysadmin friend reports the same difficulty with the program. I did try two or three "popular" alternatives but found them even worse than AWS. If you know of a more reliable utility, I'd be delighted to hear of it. Cost no object (sort of).

My "media" disk has 46000 files, using 2.9 TB of a 4 TB drive. This works fine using SyncBackPro v. 5 on a Windows 7 x 64 system with 12 GB of RAM.What operating system are you using and how much RAM do you have? You might look at the performance monitor to see what is happening. If your system is paging then you might just benefit from more RAM (if possible).
SyncBackPro allows for multiple backup jobs which would probably make it possible to go beyond any limits, were they to occur. It also allows different automatic synchronization strategies when running unattended. I migrate new files to the NAS when they are found and alert on any other changes. (I don't want a file on my local disk that got modified because of "cockpit error" to automatically corrupt the backup.) I also use the program to manage several web sites that are on hosting servers as well. (For making an offsite backup of my NAS I run it on the Windows 7 machine which accesses the NAS over the network and which accesses the backup drive over ESATA from the Windows machine.)
The SyncBackPro web page says they are on version 7, but I am still running version 5 which works fine and upgrades aren't free.
