I am running TM on an iMac with 10.5.8 to a Duo running 4.1.6. However I am getting a failure about once a day where TM pops up a dialog saying the network volume could not be mounted because of a problem with the username or password. It is very odd because it will do its hourly backup just fine for some period of time (a day or maybe a bit longer) before giving me this error. If I go to the TM Preferences I have to re-enter the username and password, then all is fine again for a day or so. This happened again just now and I snagged the Duo logs and also took a look at the Mac log. On there I see this series of possibly related messages:Aug 16 17:07:40 Kobe kernel[0]: AFP_VFS afpfs_mount: /Volumes/ReadyNAS, pid 4993Aug 16 17:07:40 Kobe Bonjour Mounter[267]: DiskAppearedCallback diskDescription = {\n DAVolumeKind = afpfs;\n DAVolumeMountable = 1;\n DAVolumeName = ReadyNAS;\n DAVolumeNetwork = 1;\n DAVolumePath = file://localhost/Volumes/ReadyNAS/;\n}Aug 16 17:07:42 Kobe [0x0-0x14c14c].com.apple.systempreferences[4987]: chown: /Volumes/ReadyNAS/.001ec20ffc9e: Operation not permittedAug 16 17:07:43: --- last message repeated 1 time ---Aug 16 17:07:43 Kobe kernel[0]: AFP_VFS afpfs_unmount: /Volumes/ReadyNAS, flags 0, pid 4998Aug 16 17:07:43 Kobe Finder[161]: StatusMonitor::volumesChangedCallBack returned -47Aug 16 17:07:43 Kobe kernel[0]: ASP_TCP do_thread_read: no reqInfo found for reqID 1Aug 16 17:07:43 Kobe Bonjour Mounter[267]: DiskDisappearedCallback diskDescription = {\n DAVolumeKind = afpfs;\n DAVolumeMountable = 1;\n DAVolumeName = ReadyNAS;\n DAVolumeNetwork = 1;\n DAVolumePath = file://localhost/Volumes/ReadyNAS/;\n}Aug 16 17:07:43 Kobe kernel[0]: ASP_TCP CancelOneRequest: cancelling slot 29 error 89 reqID 30 flags 0x9 afpCmd 0x14 so 0x7e7a330In Duo afp.logAug 16 17:07:42 cnid_dbd[29190][logger.c:255]: I:Logger: doing log_setup, type 0, level 50, filename "/var/log/netatalk.log"Aug 16 17:07:42 cnid_dbd[29190][logger.c:395]: D7:Logger: log_file_arr[0] now contains: {log_filename:/var/log/netatalk.log, log_file:(nil), log_level: 50}Aug 16 17:07:42 cnid_dbd[29190][logger.c:398]: D5:Logger: log_setup[0] doneAug 16 17:07:42 cnid_dbd[29190][main.c:210]: I:CNID: Setting uid/gid to 0/0Aug 16 17:07:42 cnid_dbd[29190][main.c:309]: I:CNID: Startup, DB dir /c/.timemachine/.AppleDB Any idea how I prevent this from happening? It means if I'm not in front of the Mac for awhile the TM backups stop.

An update, this error happened for the second time today. This time when it happened I opened up the Keychain to ensure the username and password are stored there correctly. They are and there is only one entry in the Keychain.At the time this most recent instance occurred I was doing I large copy from the NAS drive to an external USB drive. I'm wondering if there is a time out.

Same issue here, on multiple Macs running 10.5.8, ReadyNAS NV+ running 4.1.5.

After having seen this error regularly it has recently stopped appearing. I upgraded to Snow Leopard Friday and haven't seen it since then. But the errors stopped appearing about a week before that.

Is Time Machine working for you under Snow Leopard?

Yes, I expected trouble but it has been trouble free.

Just had the error again. Hadn't had it in several weeks (since clean installing Snow Leopard, really). Wasn't doing anything unusual. Safari, Firefox, Adium, Apache2 are the only apps running.

System: Macbook (Late 2008 Unibody), OS X 10.6.1
Network topology: NAS to Airport Extreme (Dual Band) via CAT6; Macbook to AE via 802.11n (5Ghz)
TCP Retransmits: 811
Unrecovered TCP Retransmits: 38
(This is after the NAS has been up for several weeks and done many TM backups; don't have numbers from before the error unfortunately)
Shares: AFP only (no CIFS). Guest access on AFP enabled. Pretty much all other services are OFF.

Hi there

I have been having the same problem (since I upgraded to a dual band AE) - TM fails with an error message "The backup was not performed because an error occurred while copying files to the backup disk" I haven't been able to complete a back up since a day after I installed the new AE.

Thanks in advance for any help or advice.

Wow you must have a lot of devices.

I have dual band AE and TM on the ReadyNas is working fine on my Macs running 10.5.8

So Netgear, have you been able to reproduce this issue in-house yet?

9 users reporting the same exact problem across multiple OS's (Leopard+Snow Leopard), multiple network topologies, and multiple types of Macs. Only common thread: the ReadyNAS.

I'm one of the 9. I see see this happen regularly on multiple Macs. Since it seems to just cause a miss of a single backup I don't worry much about it. At least in my case the backups always seem to be successful the next time.

Netgear is officially advertising Time Machine functionality. This functionality is not 100% working.

Therefore, I would like to see some attempt to address this problem other than blaming the network. If they cannot or will not address a problem with the feature, then they should not be advertising it.

Any response, Netgear?

Just a follow-up from a long time ago..

This *still* happens to me. And I've since replaced every switch and router in the house with gigabit capability.

Same problems.

Every other Mac backing up to Time Capsules "Just Work" -- it's the ReadyNAS for sure.

Wonder if Netgear has made any headway into figuring this out?

Having some Time Machine of my own here, was also getting this "Error (-36)" that I noticed in Console when trying to copy files over yesterday to a different share on the device. Details below:

dmoffitt, you have a different issue. This thread is about intermittent Time Machine failures to the ReadyNAS where the error reported is
The network backup disk could not be accessed because there was a problem with the network username or password.

and the backup fails to even begin.
