Memory Footprint On Large Data Sets?

Recommended Posts

Hello All

 

I copied all the Files of one file server to a brand New ReadyNAS 104 (about 3 Terabytes of files). After that I tried several times to let it finish sync (it only compares the Files, as I see it, there are no data copied). It always starts very fast, but after a while it takes forever to sync as more and more files are inside the dataset.. any thoughts on that? The idea is that the ReadyNAS creates a exact Copy of my Business Files at home, so I have an automated Offside Backup. 

 

The ReadyNAS has only 512 MB RAM. I suspect, that it cannot cope with a Database for 120'000 Files in 3 Terabyte of date.. could that be the reason? Any other ideas?

 

regards, Urs

BTSync consumes around 400 bytes of memory per file(folder). So, 512 Mb RAM should be enough to track all the 120k files. You can try to run

top -p <PID_of_BTSYNC>

command to see how much memory (in percent of all available system memory) it consumes - and get some feeling if it has enough memory.

 

Also, are you using 1.3.106 build? There was important fix related to the indexing of files.

The Problem is that NetGear has not released an update to 1.3.106 ... so I am stuck with what they have on their App Store  :-(

 

On one Computer that is syncing the Memory Footprint is About 216 MB .. but it has more folders to sync. But still, for some reason things get very slow, the more files there are..

We are working with Netgear to deliver the latest version to the package. Also, you can replace the binary yourself if you have the SSH access to the box.

I would also suggest trying to increase folder_rescan_interval to 1 day as a test (due to numerous files it looks like it takes a lot of time to rescan folders). Though, it will require SSH access as well - config mode requires you to run binary with "--config" switch.

How is the state of the Bittorrent for ReadyNAS? No update to see anywhere..?? Would love to update on all machines.. What happens If I use 106 on every machine but 105 stays on my Ready NAS?
