Hello all!This is my first post here so forgive me if I'm asking something i did not find in the forums already.We have lots of sites with the NV+ NAS and here is our setup;ESX4 with Vranger 4 backing it up to a daily share on the NV+NV+ built in backups backing up the Daily share to USB drives: specifically the Seagate EXTREME 1TB modelVranger backups are NOT running at the time the NV+ is trying to backup to USBfor some reason it takes forever to backup to the USB drives, were talking 24-72 hours for 200-300gb of datahas anyone else seen this issue? Why would the NV+ be sooo slow backing up to USB 2.0 drives plugged directly into the back USB ports of the NV+??Thanks in advance!Clay

How did you format the external drives? EXT3 is fastest. NTFS seems to be slower.

Remember to properly unmount the disk if you check this option:http://www.readynas.com/forum/faq.php#How_do_I_improve_write_speeds_of_USB_External_Drive_attached_to_ReadyNAS%3F.B52hbuff wrote:EXT3 is fastest.EXT2 is faster actually.B52hbuff wrote:NTFS seems to be slower.Yes it is. FAT32 (has a 4GB per file limitation) is in-between NTFS and EXT3 performance wise.Another thing to be aware of is: Does your USB disk have a sleep timer? If so, connect the disk up to a PC, run the utility, tell the drive never to go to sleep, apply the changes and disconnect it from the PC.USB speeds still aren't going to be that great on the NV+ (slow CPU etc.). The NVX, Pro etc. can do USB backups quicker and have decent speeds backing up to disks formatted using the NTFS filesystem.

Certain external drives (both 2.5" AND 3.5") cause BIGTIME slowdowns in the web interface AND the backup times.Most external drives have no utility to turn off sleep timers. I've been using Seagate drives as I can use their utility to turn off the sleep timer.This issue happens even before the drive goes to sleep. I have more than 20 ReadyNAS (NV+ and Duos) in businesses and ALL have this problem if the drive has a sleep timer turned on.Also - backups seem to go a bit faster if you change out the RAM to say a 1GB module.But no matter what - the initial backup will take DAYS depending on how much data there is to back up. I'm waiting for a new NV+ to finish its first backup of 156GB, it's taken 34 hours so far and it has 3GB to go.

Ok thanks for the replies!I have shut off the sleep mode on the seagate drives by direct connect and using seagate manager.I have a question about the fast writes: I get the following info next to the option:"This option speeds up USB write access by accessing the USB device in asynchronous mode. If you enable this option, do not remove the USB device without properly unmounting it. Failure to do so can compromise data integrity on the device."I am wondering if this means that every time the client goes to take it off site after backup completion they have to dismount it first? I don't want the client to have to anything but disconnect it and take it offsite. Id hate to see them corrupting the data by unplugging it to take it with them offsite.

I'm not certain this is correct, at least not for the 4.1.8 version running on the NV+. I can certainly vouch for the fact that USB backup using 4.1.8 on an NV+ to a NTFS USB drive is brutally, painfully, impossibly slow.

if your performance is slow then there's not much you can do except make sure you use incremental backups.

Yeah but you gotta get the initial backup made.

I do wonder if it's possible to change the priority of the backup command within the NV+ to make it work faster. As it seems now, the USB transfers are the lowest of the processes, at least for my NV+.

Make sure you have Fast USB Writes enabled. You may need to reconnect the drive after enabling the option.

The quickest way to do the initial full backup is to connect your ntfs drive to a pc, connect the pc via gigabit Ethernet to your nas and do the first copy that way.

Not sure if this will retain file ownership and permissions though, so you might just want to take the hit of doing the initial backup directly from the readynas to be safe. Worst case a 2TB backup should run for less than a week.
