Backup & Archival Plan–eSATA, SAS, & BOB.
Okay so the title was intended as an attention-getter–Hello! 🙂
I have a need for a better backup system for the office (1 Mac Pro and 1 MacBook Pro) locally that can also be used to rotate media off-site. At the moment, I am using Retrospect & Time Machine on one of my internal Mac Pro drives and a GTech 500GB FW800 external drive which is sometimes off-site. My immediate need is to backup: pictures, music, databases, virtual machines, AppleTV Movies, and other documents which is about 1TB. I’m slowly ripping my DVD collection for use via AppleTV and I plan to start scanning ALL of my old photographs and negatives…. so my movie, music and photo library (Aperture) will grow rapidly. Also, this backup system could possibly allow me to archive FCP projects and media.
Anyway, I obviously need to backup with greater regularity, redundancy and security and I know I need a better system in place to accomplish that. At the moment, I lack the ability to easily move data off-site and I could use more space that is dedicated for backups. For backups I actually prefer tape (LTO-3 or LTO-4) or backup files that are NOT Finder readable. That way you will never get confused and edit the backup and not the original which would cause you to lose your changes when the backup set is recycled.
Cost Effective Media: I have not done an exhaustive analysis; yet, it seems that tape is about the same as a HD (hard-drive) based solution and that tape seems to be slower performing and relatively low-density native capacity (without compression) which would require handling many tapes.
What HD backup system? Assuming that an HD-based solution is best–what enclosure system? I would like at least two backup HD volumes (if not 4 or 5) to be online at any one time. Call the local drives (or collections of drives) A and B. Every night either BackupSet A or B is used to backup incrementally (where prior versions of files are retained) and weekly Backup Volume C (previously off-site) can be exchanged for Backup A–now A is moved off-site. I guess there should be two off-site volumes to avoid EVER having all backups in one area such as during the drive swap. Also, I like the one cable idea as afforded by port multiplication and some units have FireWire where that single cable can reference ALL of the drives in the external enclosure. For the moment, I would probably just use FW400 or 800 connectivity if the box supported such flexibility and later I would want the option of using eSATA or SAS, etc… If I started using SATA now, I would hope that one interface card could support my backup enclosure and an external RAID. Is that possible now?
Sonnet has a nice enclosure such as the: FusionD400Q https://www.sonnettech.com/product/fusion400quad.html I like that this model has: flexible interface options (FW800/400; USB2l eSATA) that only requires one cable and that it has an internal power supply…. It’s pricey and may be over-kill for just a backup or archival enclosure. Also, the trays are expensive compared to others. And of course there are tray-less designs from companies like Wiebetech.

This one is eSATA only.Firmtek has:

SeriTek/5PM https://www.firmtek.com/seritek/seritek-5pm/Wiebetech has:
RTX400 https://www.wiebetech.com/products/RTX400.php
RTX100 https://www.wiebetech.com/products/RTX100.phpSo, what are you using for backup or archival?
BTW: this backup plan could also be applied to Archival of projects as well (even though disk drives are not expected to be as reliable as tape during long periods of inactivity which requires periodically mounting the drive). I would make more than one copy and store them in different places if failure is not an option… With all of the tapeless acquisition, this is a big challenge to archive the media reliably. I don’t want to have a bunch of cheap FireWire drives all over the place… I would rather use the drive mechanism themselves and store that in box on the shelf, etc. This should also be more cost effective.
Definitions:
Backup: a copy of the original, to be used to restore the original if necessary.
Archival: moving the original to a long-term external storage medium.So, I’m hoping that your response will help me to make a wise decision about this need so I can stop thinking about it so that I can begin to enjoy benefits of such a system. So, Bob, what do you recommend?
Thanks
