View Full Version : Backup to NAS Network attached storage; confused

09-25-2007, 08:11 PM
I just bought a ReadyNAS (http://www.netgear.com/Products/Storage/ReadyNASNVPlus/RND4450.aspx) for my small office. I'm wondering if it's possible that I can backup my MacBook Pro to a sparse image on the NAS (4HD, 1.3TB space, RAID-5). Page 18 of the user guide makes me think I can do this no problem. But on Page 19, I see the note box:

Note: Itís very important that the network drive support files larger than 4GB. FAT32-based servers or NAS devices will not work, and fail pretty spectacularly when this limit is reached. Please ensure the network volume is HFS+, NTFS or ext3, all of which support large files.

That indicates to me that my NAS drive won't work for this sort of backup, and that I should just backup my laptop to a FireWire drive or something.

I've read these forums but don't see a definitive answer to this - or any specific reference to that note. Thanks for any insight.

The caveat is that FAT-32 based NAS devices won't work. The ReadyNAS will work fine.

Oh, I see. I was reading the sentence wrong - or misinterpreting it.

"FAT32-based servers or NAS devices will not work" is the phrase.

To me that meant:
FAT32-based servers will not work.
NAS devices will not work.

When in reality that means:
FAT32-based servers will not work.
FAT32-based NAS devices will not work.

Thanks for clearing that up, that's good news!

Yes. Not my best sentence...

Now I'm trying to backup a portable USB drive I have to a spareseimage on my new NAS. I've followed the instructions in the user guide, but the spareseimage won't mount after it is created. I'm getting this error:

| 02:03:17 PM | Info | created: /Volumes/backups/usbdrive_backup.sparseimage
| 02:03:17 PM | Info | ......COMMAND => Setting ownership and access modes for '/Volumes/backups/usbdrive_backup.sparseimage'

Looks like I'm missing something - should I reinstall SD? I tried connecting to this share via smb and afp, but it wouldn't mount after creation in either case.

No. You need to delete that plugin, which is not compatible with your Intel Mac.

Will do - I thought it looked odd. Thanks for your quick reply.

I'm looking to get a Linksys NMH300 NAS solution. I understand that I can keep those disks in NTFS format to make the backups in SD. Will the images of my MacBook Pros be truly bootable? I guess I thought the drivers want HFS+ format to boot. Any guidance is appreciated. Thanks.

No: no NAS volumes are directly bootable, Dan.
