Startup Disc and Hard Drive Partitioning Questions

[dnanian]

Just remember that your 1.5TB, if you're going to use SD! to copy to it, can only be used for that purpose. If you want to store other items on the drive, you'll want another partition.

iPartition (and Disk Utility in some limited situations) can change partition sizes nondestructively.

Thanks, What do you mean by? "If you want to store other items on the drive you'll want another partition". Please explain.

The "Mac HD Backup" partition would include the OS and all applications. (And would be "Bootable")
The "Artwork Backup" partition would include video, 3D, graphics, word files etc. (Not Bootable)

Not sure what another partition would be used for. Do you think I've given too much for the "Artwork Backup" partition? Please explain!

Are these the correct instructions to format my 2TB external drives.

Smart Update, as it says, is like erase-then-copy. So you put other items on a volume that you smart update, those items will be removed when you smart update.

If your source drive is a 100GB drive, then 1.5TB is, indeed, too big. But if it might grow to 1.5TB of data, then it's not. Much of this is stuff you kind of have to decide for yourself...

Question 1
If the 2TB Drive has 2 partitions. one named "Mac HD Backup" and the other named "Artwork Backup" then don't I just choose the one I wan to back up to and use "Smart Update"? For example if I select the "Mac HD Backup" partition and select "Backup All Files" and "Smart Update" then it will clone the Mac Hard Drive and Copy over the files needed but won't touch the files in the "Artwork Backup" Partition. Copying files to one partition won't affect the other partition. Is this correct?

Question 2
I have spent a lot of time going through the steps (see below) I think I need to take after I partition the drive into 2 drives. Please tell me if my steps are correct as I need to do this tomorrow. Thanks.

To backup to: "Mac HD Backup"(This is the 500 GB partition in the 2 TB Drive)
You want to crate a "Clone" or exact copy of the Mac Hard Drive which can be "Bootable" in case of Hard Drive Failure.
1. Super Duper - "Backup Script"
First Time Backup Use: "Backup All Files" (Clones/Copies the Mac HD and will create a "Bootable" backup in case of Hard Drive Failure you can boot from this.)
Second or Third Backup Use: "Backup All Files"

2. Leave "Repair Permissions" unchecked.

3. Super Duper - "During Copy Setting"
First time Backup Use: "Erase Backup, then copy files from Macintosh HD" to backup the Mac HD (this will create a "Bootable" backup)
Second or Third Backup Use: "Smart Update Backup from Macintosh Hard Drive" to backup the Mac HD (this will create a "Bootable" backup but will only copy or delete files and folders as necessary taking less time.)

To backup to: "Artwork Backup"(This is the 1.5 TB partition in the 2 TB Drive)
You only need storage space for artwork and other files and you don't need it to be "Bootable".
1. Super Duper - "Backup Script"
First Time Backup Use: "Backup - User Files" (this is for storage and is not a "Bootable" backup. Good for storage of files)
Second or Third Backup Use: "Backup - User Files" (this is for storage and is not a "Bootable" backup. Good for storage of files)

2. Leave "Repair Permissions" unchecked.

3. Super Duper - "During Copy Setting"
First time Backup Use: "Erase Backup, then copy files from Macintosh HD" to backup the Mac HD (this will create a "Bootable" backup)
Second or Third Backup Use: "Smart Update" or "Copy Newer Files from Macintosh Hard Drive to Backup" to backup the Mac HD (this will create a "Bootable" backup but will only copy or delete files and folders as necessary taking less time.)

A1: Yes, that's why it says that in the interface.

A2: always use "Backup - all files" with "Smart Update" for both drives (since you're starting out with empty drives anyway, there's no reason to use erase-then-copy the first time). Do not use "Backup - user files". "Backup - user files" backs up your Home folder(s). Your Artwork drive does not have home folders.

Thanks Dave.

Instead of partitioning my 2 TB drives I have decided to return my 2 TB drives for (2) 1 TB drives. I will back up my OS and Applications onto a 300 GB drive and use the 1 TB Drives for storage only. These drives will only hold data files such as: Graphics, Audio, Video. Images etc.

When Should Journaling Be Used? - Journaling is best suited for servers requiring high availability, servers containing volumes with many files, and servers containing data that is backed up at infrequent intervals (nightly, for example). If a volume contains read-only data that is not mission-critical, it may not be necessary to turn on journaling if performance is more important than safety. If your server contains high-bandwidth usage data files, such as large video, graphics, or audio files, you may want to weigh the benefits of using journaling against the performance needed to access your data. In most cases, the impact of journaling upon data access performance are unnoticeable to users, but its implementation may not be practical for servers where data access demands outweigh its benefits. - Apple

After reading this article I am not sure which is better. "Journaled" or "Not Journaled". They talk about performance being more important than safety. Does this mean if I don't use "journaled" that my data is at risk of being lost? I want the drive to be used for storage so which is best IYO? "Mac OS Extended (Journaled)" or "Mac OS Extended"

Thanks
