questions about RN424 and RN524 new models
I have been a very happy Ultra 2 Plus user for quite a while, currently running OS6.8.0. I am a little frustrated, however, by the 2gb memory max capability, crashplan is a memory hog and I'm relyin...
My understanding is that the memory in the RN42x systems is soldered on, so it cannot be upgraded.
The RN524x supports up to 32 GB (2x16). It uses ECC memory (DDR4). As usual, this is unsupported by Netgear so it is at your own risk.
Some more details are on this thread: https://community.netgear.com/t5/ReadyNAS-Hardware-Compatibility/Memory-upgrade-for-Readynas-RN-422/m-p/1285452/highlight/true#M15958
I think it is a bit harder to reach the memory in the RN52x chassis (I only opened mine once, and that was a while ago).
well now that is interesting. I am using an Ultra 2 Plus with 2GB of ram, and I have set the JVM memory to 1.5gb max. But when my archive size on the crashplan cloud starts to get over 1.5TB it starts to crap out. Its only about 500,000 files and I have deduplication set to minimal also. I think compression is not the issue for memory, though that might reduce some CPU overhead. It is, as you said, the deduplication that causes the consumption of memory, and according to crash plan tech support, its the size of the archive on their cloud that effects the memory use. Personally I think they could do something smarter that doesn't require such a big memory footprint, it is currently a memory pig.
regarding the idea of using a PC to run crashplan, I have thought of that, I would use a mac though.
But I would assume that file permissions would be lost in the archive that way, at least owner perms would.
If I buy an RN524 and load it up with 4 drives, its not a stretch that I will eventually be backing up something like 5-10TB of data, I don't see it getting much bigger then that, but hey, never know. Anyway it sounds like 4GB of ram might work for 5TB, but honestly I would probably prefer to have it upgraded to at least 8GB.. if for no other reason, that as long as crashplan is the preferred cost effective backup solution, and if I end up with 9TB of raid5 space...then....I need to be able to back it up....sooner or later I will fill it up...
I wish I could figure out a way to make my ultra 2 plus backup 2.5TB to crashplan....but...I don't think its possible.

Try setting deduplication to "minimal" (advanced backup setting).

It will of course just use whatever SAMBA reports. Since we are largely using it from Windows, that is ok for me. Backup speed right now is a bit pokey (despite the 10GBase-T card, which gives sequential SMB performance ~540 Mb/s). Hopefully the memory upgrade will help that.
already have it on minimal. I also have real time monitoring turned off.
I have the JVM configured for 1.5GB and right now the crashplan service keeps dying when I run it... the backup size on the cloud is right around 1.5TB. That appears to be about the most I can backup to crashplan with this device I'm afraid. I have some other things running right now that I can't turn off but when they are done I will turn off absolutely everything else and see if Crashplan can at least get to 2TB, which would cover most, not all, of my backup needs.
I also tried to set the JVM memory size to someting larger then 2gb just to see if virtual memory would cover it, but nope...the process just dies at some point.
The other way I might go with this, but rather not, is to use borg to backup my readynas over to a mac. Then use crashplan from the mac to backup the borg archive itself to crashplan. The downside is that I would not be able to restore a single file from the cloud, I'd always use the local borg archive for that and the borg archive would be for the case of my house burning down I guess or I lost the local backup, then I'd have to restore the entire complete borg archive from the cloud before being able to restore a single file.
Iwhich might be fine, but that is duplicating a lot of data on my local network, so I'd rather not, but basically I'd be taking the position that my local backup should be good enough and the crashplan backup is just in case my house burns down. With my current backup, 2TB or so, I could just as easily hook up a USB drive and use that as my borg local backup also, not a bad way to go. but I'm also trying to think ahead to if i get an RN524, which could easily become a much larger dataset to backup and backing it up locally would become expensive.

Why make it that complicated? Crashplan can back up network shares mounted on the mac. Though I do get that ownership/permissions would come from SMB or NFS, not directly from the file system, it seems to me that you'd be paying a very high price to overcome that.

Yes file ownership would be the reason. Also, it might not be so bad to have a local backup anyway. I'm still thinking about it. I agree its a lot of overhead.
