[QUOTE="wheelguy12, post: 1261029, member: 197775"] I am doing backups similar to your approach, have been for a few months. My backup server is an old Windows 2003 laptop that sits on top of my safe. From it, I have a 500gig USB drive inside the safe with the USB wire going out through a hole into my laptop. The laptop is connected to the home network (100meg speed) and, from there, 2 windows machines and 1 mac maintain constant backups. The Mac backup works like this: I created the dreaded sparcebundle file with a 700 gig capacity, using terminal commands. Actual file size is right at 1 gig. I then copied this file to the backup disk connected as a smb drive. That took a while over the 100meg network! Finally, I pointed TimeMachine to the smb drive and it has been working perfectly ever since. When the backup fills up, TimeMachine tells me to delete the old backup and start over. So, I delete the old one and re-copy the 1 gig sparcebundle file again. So, I save that PITA sparcebundle file for this recurring task - instead of re-executing the terminal commands. The terminal commands needed to create the sparcebundle have to be done exactly right - block size has to be just so, for example, to accomodate large backups. I didn't save the 2 commands that are needed since I saved the sparcebundle, but you can find the info on how to create it correctly. Just look for instructions that take account of setting the block size correctly for large files. [/QUOTE]
