firewire hard-drive

[edbeta]

i have a lacie firewire hard-drive of 7,2000 RPM of 80 GB external , after talking to two suppliers

 

of mac and video products they offer me this advice : backing-up to cd-r or cd-rw is NO VALUE

 

for my workstation ( too low capacity ) , dvd-ram not much better at short term since 4.7 GB is not

 

that much use in a video workstation , dvd-r/-rw/+r/+rw not better even if they where compatible

 

with retrospect express ( still 4.7 GB) , SO THEY TELL ME EXTERNAL DRIVE HARD-DRIVE OR TAPE-DRIVE

 

WHERE MY ONLY OPTIONS......ADDING HARD-DRIVE IS THE NATURAL CHOICE FOR ANY VIDEO WORKSTATION

 

WHERE RANDOM ACCESS IS NEEDED AND PREFERED (tape is more for accounting back-up type...).

 

 

 

HOW I CAN FIND IF MY DRIVE IS COMPATIBLE ON YOUR SITE......

 

ONLY ABLE TO LOCATE TAPE OR CD/DVD DRIVE COMPATIBLE.......HOW ABOUT HARD-DRIVE FIREWIRE

 

EXTERNAL...........

 

 

 

PLEASE HELP ME..............

All Hard Drives are supported except for on OSX Buslink Firewire is not supported.

 

 

 

Directions on how to backup to HD are below:

 

 

 

Retrospect is able to make use of space available on external USB, FireWire,

 

SCSI, or IDE hard drives for backup. Once the drive has been mounted on your

 

local desktop it can be used as a backup destination. An external hard

 

drive will not show up in the Configure > Devices window.

 

 

 

To use an external hard drive for backup, you have two options: either back

 

up to a file backup set stored on the hard drive or do a duplicate of your

 

source hard drive to your backup hard drive.

 

 

 

File Backup Sets

 

 

 

A file backup set is a single file which contains all the files you have

 

backed up, and that can be stored on any random access device. Like tape or

 

removable disk backup sets, you do incremental backups to it and it supports

 

software data compression.

 

 

 

File backup sets are limited to the maximum file size allowed by the file

 

system used to format the disk:

 

 

 

o HFS Extended (Mac OS 9.x or later required): 1 TB with a 16 MB resource

 

fork limit

 

o HFS Standard: 2 GB

 

 

 

To do a backup to a file backup set, choose "Create New" from within

 

Configure>Backup Sets. From within the backup set creation window, set the

 

"Storage Type" to "File" or "Macintosh File". Name the backup set, click

 

New, and save it on your destination hard drive. When doing your immediate

 

or scheduled backup, select the newly created backup set as your

 

destination. Are you sure you have the correct backup set selected as your

 

destination?

 

 

 

Duplicate

 

 

 

Retrospect offers another option for copying data to a hard disk; the

 

duplicate feature.

 

 

 

The first duplicate operation will copy all files from the source volume,

 

keeping them in Finder format. Subsequent duplicate operations will be

 

incremental, copying and replacing files that have been modified or are new.

 

Identical files are not copied again.

 

 

 

What is the difference between Backup and Duplicate?

 

 

 

o Backup copies files in a proprietary format only accessible using

 

Retrospect. Duplicate copies files in standard file format so they can be

 

opened or used right on the backup disk without having to go through

 

Retrospect.

 

 

 

o Backups offer optional compression, not available with Duplicates.

 

 

 

o Backups offer optional encryption, not available with Duplicates.

 

 

 

o Backups can save old data incrementally so files deleted from the source

 

are still available in the backup. Duplicate basically keeps a mirror image

 

of the source so each duplicate operation overwrites previous data and only

 

retains the current files.

 

 

 

o Backups can span multiple pieces of media. Duplicates are always a

 

one-to-one operation; one volume is duplicated to one volume. If you have

 

multiple volumes to duplicate you will have to create an empty folder on the

 

destination for each disk you wish to copy. You can then define those empty

 

folders as "Subvolumes" from within Retrospect. This will allow you to copy

 

Source volume #1 to Subvolume #1 and Source volume #2 into Subvolume #2. The

 

Retrospect User's Guide contains detailed instructions on how to configure a

 

folder as a Subvolume.
