I am having problems backing up data that I have on a Network attached storage (NAS) device (Buffalo Linkstation). When I do an image backup of my C: drive to a hard drive attached via USB (O: drive) to the NAS, TI works great. I can mount the backup and restore files from it. When I try to do a file level backup of the files on the NAS (N: or \\link1\share\) to the drive attached via USB, TI fails with the following errors: 1) Error opening the file. (0x40007) Tag = 0xF35F747B3B21FA89 2) Failed to determine corresponding partition for path '\\Link1\share\'. Backup operation will not snapshot that path 3) Create Full Backup Archive. From:\\Link1\share\ To file:"O:\LINK1_SHARE Acronis File Level 8-4-2006.tib" Compression:Normal Description: "File level backup of NAS share drive (N 8/4/2006" I believe the NAS stores files in EXT3 format (Linux/Unix?) but they are visible and accessible as normal files thru Windows Explorer. I’m running XP media Center edition service pack 2 and TI Home version 9.0 build 3677. I’d appreciate any help you can offer. Thanks.
