Please advise on the best backup
Hi i am new to SD (as i am evaluating it) at this moment it looks very promising!
Below is what i am using for the evaluation: MacBook Pro 15" Unibody (APR'09): With 2 partitions, one for the OS (Snow Leopard) and one for DATA Freecom USB 2.5" 250GB External Harddrive With 3 partitions, one with a copy of the SL Installer DVD, one OSX (10.5.8) Boot partition (with SuperDuper installed), and one for Data. Question: Can i create a backup (read only image) of Snow Leopard boot up partition on the MacBook Pro, when i bootup from my external USB HD. Or should i boot from my MacBook (SL), install and run SuperDuper from there and do the backup? Thanx for your advise Last edited by xslord; 09-03-2009 at 05:52 AM. |

You should not copy Snow Leopard from Leopard, no. And I would suggest a read/write image, not a read-only one (which is slow and can fail during conversion if any I/O errors or disk space issues occur).

So if i understood it correctly i should create a backup of SL by booting and runing SD from another OSX startup (like from an external boot drive or another boot partition)?

No, it's fine to copy the drive you're running from... but if you want to start up from an external HD, you should be running Snow Leopard to copy Snow Leopard.

Hi dnanian
Thanx for your reply, could you be so kind and explain why it is better to create an SL image from an external startup which is also SL? Cheers |

You're going to get a more accurate copy if the drive isn't in use, since its files won't/can't change. However, in the vast majority of cases, those changes have no real effect.
