So there are two primary backup methods provided in frontview, for purpose of backing up my volume data. There is the so called "File Backup" and there is ReadyDR. I'm assuming my machine (524x) supports ReadyDR, but I'm wanting to understand what exactly the differences and pros and cons of ReadyDR vs one of the various file Backup methods.. For now assume local backup, not network... For the FileBackup backup, what method is used to copy the files? cp? rsync? what is actually used to make the backup? Does it do anything incrementally? Any checksumming or other verification steps? Does it create a temporary snapshot before performing the backup? All user permissions are 100% preserved. ReadyDR seems interesting, for one thing it looks to me like it copies at a lower level, and pulls over all snapshots along with it. I'm not sure I need that but I understand the benefit. But as I understand it, the destination is not a usable clone, its the underlying snapshot data, but I read SandShark say that there is a fast operation to turn one of the snapshots into a usable clone. I don't know if that's true? I would definitely like my backup to be immediately usable without a neccessary restore step, but this may be ok with readyDR if there is a short operation to make a snapshot available in some way to the filesystem, as a neccessary step, that could be fine too. But I want to understand what are the pros and cons and gotchas related to readyDR or whether I should just keep it simple and do basic filebackup. I do intend to create daily snapshots on the backup destination. I realize already that these will not be coordinated with the source snapshots (if and when they exist), but will be good enough for me to simply have timemachine style snapshots on the destination which i can do if the destination is BRTFS JBOD drive in bay#4. So I'm kinda leaning towards just using filebackup method rather then readyDR, but I want to make sure I'm not missing any other advantage that would make it worth consideration. Also for file backup, is there any reason to use network backup to local host to force some particular protocol or better to just do local with whatever copy method is being used?Can I shelf a JBOD volume for later?
I have it in my mind to use drive bay #4 as a JBOD brtfs backup drive. Primary RAID1 will be in drive bays 1,2. I may have also an additional JBOD drive3 with intentionally non-raided data. The desire is to backup both the RAID1 volume and JBOD volume to drive#4 JBOD btrfs. I have thought about getting an external USB drive as a backup drive, however my understanding is that external drives can't be formatted as btrfs, they would need to be EXT4 most likely...and one thing I am hoping to do is to do timemachine style snapshots on the backup data. So first question, I'm I crazy with this notion or fine so far? But the quesetion comes up, what happens if the first two volumes die or need to be rebuilt and let's say its the first /data volume on RAID1 that has to be rebuilt (or maybe I just want to expand it), so I guess I would have to at that point pull all the drives out (including the backup drive) and do a factory reset with two drives in RAID1 and setup readynasOS to my satisfaction, then introduce the backup JBOD Volume back in, but can I do that? Is there a way to insert that shelved JBOD backup drive, while I do a factory reset and then insert it and have the readynas see it, is flex raid smart enough to do that? Or would have to have the backup on some totally external media in order to avoid flexraid requiring that JBOD volume to be wiped? Is there a way to use brtfs on external USB drives? Not for purposes of raid. but for snapshotting?Solvedchecksumming outside of raid?
I am just curious if anyone here is doing any supplemental checksum checking of their data beyond what btrfs does, for example to check the data before backing it up to an external source...or comparing checksums of the main volume vs backup volume, etc, etc, etc, I know about md5sum....and there is an interesting utility called chkbit which can be setup to keep track of checksums for every file and uses the the timestamp to determine if the checksum needs to be updated, etc.. so it may be possible to run periodic scans to look for checksum mismatches, which might be bit rot or other glitch-caused data errors in the data. Generally I think this is not needed if the BTRFS raid1+ array has been kept healthy at all times, but I plan to use chkbit on my desktop computers to check for bit rot there and might put it on readynas also as an extra check to make sure the raid is not missing anything..and particularly I thinking I should put it on my backup volume which is not raided...and maybe compare the main raid volume against the backup volume or something of that nature... Well just wondering what if anything others may have been doing in this regard.SolvedLauncher app sometimes has trouble connecting on my Netgear router
Hi all, I’ve been using a small Roblox launcher tool called BLXStrap and I noticed that sometimes it struggles to connect or download updates when I’m on my Netgear router. On other networks (like mobile hotspot or a friend’s WiFi) it works fine, so I think it might be something with my router setup. Has anyone else run into issues with custom apps or game launchers having trouble connecting? I’m wondering if it could be: Firewall settings QoS / traffic prioritization Or maybe something like DNS resolution I’m not super technical, so I don’t know what to check first. Any tips on what settings I should look at to make sure apps like this can connect without problems? Thanks in advance!ReadyNAS snapshots
Can anyone please clarify how the snapshots are structured in ReadyNas OS? I see that when I create a snapshot is there in front view. If I have checked the box to "access the snapshot" (for a share), then two new folders show up at the root level of the share. "snapshot" and ".snapshots". .snapshots is totally hidden from ls listing even in ssh, but if I cd to it anyway knowing is there, I can cd into it. It appears to me that .snapshots is meant to be the internal location of hard links to underlying snapshot references, they are numbered 0-9 so far. Then the other snapshot folder that is not hidden is also referencing the same things...but labeled as dates rather then sequential numbers. First I want to understand if I'm understanding that correctly so far? I am trying to setup my idrive backup to ignore those because to idrive, due to hard links, they just look like lots and lots of duplicated data...twice...once for snapshot and once for .snapshots. Still trying to figure out out how to exclude them in Idrive, idrive has an exclusion list, but somehow so far its not excluding them..and it takes a really long time to prep its backup task...I guess scanning through many many more data then necessary. I will probably figure that out eventually, but for now just wanting to understand how the snapshots in Readynas work...in terms of those folders when I have enabled "access" to the snapshots. I wish Readynas had located these access at a different path inside of at the root level of the share, because while readynas is presumably smart enough to ignore that when creating each new snapshot, avoiding recursion.. other tools such as idrive and others, simply see it as a lot of duplicated data. well anyway it is whatever it is, but any clarity on this point would be helpful. thanks.Which Modern NAS?
Well, given my recent loss of ReadyNAS functionality due to drive failures on two drives, loss of my RAID5, factory reset, followed up inability to install build-essential and Medusa... I am contemplating a more modern NAS replacement. I may or may not just continue to use my 524X in whatever limited capacity becuase for basic file sharing..it still works fine. It even still runs Plex. But not Medusa... Anyway just wondering what some of you think about current modern NAS that are available, in comparison to Readynas OS6 For reference, my 524x is intel with memory upgraded to 16GB (I don't remember if its ECC or if Readynas can even properly use ECC). So I am thinking about TrueNAS, but first question is what you guys think about ZFS vs BRTFS? I have been poking around and thinking about a Terramaster F4 with 6 bays, the max version is a pretty decent i5 processor in it that is capable of virtualization, especially if I upgrade the RAM, and basically it would do everything the Readynas does not, and a lot more...and able to upgrade to new versions of linux, both in whatever TrueNAS is using or virtualized VM. Can even run Win11 on a VM in that setup. or might use proxmox...haven't decided... or open to other ideas.. The Terramaster apparently does not support ECC memory, I'm not sure how critical that is. But its easily supports installing any OS I want, its basically just more of an open ended PC. Qnap i guess make pretty good hardware but I need to investigate more. Anyway just wondering what some of your thoughts are. I might just keep using my Readynas for a few more years in this more limited capacity, it basically is working now, the only annoyance to me is that I have to run Medusa somewhere else. My hot rodded 524X handles all my plex needs just fine, I typically am not doing heavy transcoding anyway. But still I have to run an entirely separate old PC on the side just to host Medusa and some occasional utorrent, neither of which are realistic on the current readynas status quo. So getting a more modern NAS that can handle those two tasks and something more able to run modern linux or even win11 is probably what I will eventually do...even if I run the reasynas for a couple more years this way in limited capacity but just wondering what hardware and/or software solutions some of you are considering for future NAS...and in particular it seems to come down to two main filesystems people are using for NAS either ZFS or BRTSFS.. What are the pros and cons between these two. Personally I am not interested in ever running RAID5,6 again. It has bitten me in the butt twice now, losing data. In the future I will use RAID1 mirroring only. But one thing about ZFS that seems interesting is you can put two RAID1 mirrors into a larger pool, and have one very large volume based on two mirrored arrays. But anyway I'm sure there are subtle differences with BTRFS and ZFS advocates on both sides, but just curious what some of you would say about BRTFS vs ZFS, and in general, what modern NAS are you keeping your eyes on now that Readynas is going extinct?RN104 file transfer speeds
Hello, I've always had my rn104 connected to a gigbit ethernet switch and I get 10 - 12MB/s file transfer speeds to my windows 11 pc. I set static IP addresses on my nas and pc, ran a short(6ft) cable directly between the 2 and I'm only getting 15 - 16MB/s. I expected much more. Any Ideas as to why so slow? The RN104 has old 5400 rpm desktop 4TB hard drives. Could they slow transfers down that much? Thanks for any assistance rendered, TomRN316 local config file ?
Hi, We have a RN316 6 bay device in one of our remote offices, The local IT tech decided to pull the drives and appears not to have installed back in the same slots. My question is . Does this device have a local config file that details the original slot configuration ie slot1 serial 12345 slot2 serial 3456 slot 3 serial 7890 etcReadyNas 102 new hdd not detected
Hello, I just bought a new HDD ( ST2000NT001 - Seagate IronWolf 2 TB) but when I insert it in my readynas 102 it is not detected. I know that this disk is not in the HCL (hardware compatibility list) but so far I have a SDD that was in also inserted in the readynas 102 and it is correctly detected even tought this one is not on the list either. I tried many thing including : many factory reset (either from the Web UI or using the super intuitive paperclip mecanism) inserting only one disk putting the disk on the tray and inserting half of the tray (to be sure that the disk is connected to the SATA + alim port) using a physical disk cloner to clone the working SSD on the new HDD inserting it in slot 1 or 2 either with another disk or all alone I connected the HDD to another machine and it was well detected by gparted (I could manipulate it, create partition and stuff). The ReadyNas was using something like ReadyNasOS 6.2.5 and I managed to update it to 6.10.10. This update didn't solve my problem. So, to sum this up: The NAS is still working, it's firmware is up to date, the disk is new and working - detected on any other machine but not on my NAS. Any help and idea is welcomed as I fall into despair.Solved
