How to backup P2

I use Panasonics P2 system with Edius Broadcast and am very happy with it.

I shoot everything in HD so end up with a lot of footage that needs archiving. I normally end up with about 300gb of data per week !!!

This is to big for DVD and blue ray and rev pro.

I have been using a LTO 1 drive I got off ebay for £100 using windows backup.


This is very slow it takes about 10 hours to backup 100gb of data !! and another 10 hours to verify the data…

Also the windows backup utility is very basic. It cant even tell you what’s on a tape when you insert it in …

The only backup softwhare that works with LTO tape is for server machines.
There must be something better…….



What do you use to back up all that HD Data???
 
esata or firewire 800 raided drives might be a good bet for you if you want an external solution. or even going internal raided. but in the end, most of your speed is gonna be throttled at the speed of the p2 reader you have...
 
I don't shoot as much footage as you per week- yikes ;-). I've given up on backing up to media, so I just use duplicate drives to back up all footage. One is stored off site, the other kept at hand.

Burning to media is just too time consuming given the rather small-ish capacities. I've not yet used blu-ray, so that may change my outlook on the matter.

Why don't you use a Lacie drive like this? A 500gb replacement drive is $149 but maybe you could get them significantly cheaper if you bought in bulk. Just a thought?
 
Long term high volume data storage that doesn't require access is basically tape these days.

We use bare SATA drives with a removable SATA drive enclosure (dual), and store in static bags or carriers.

Fast and works well
 
Hard drives are not a legitimate LONG TERM backup solution.

I spoke about this in depth in my 2008 NAB P2 workflow seminar at Post Production World.

I asked everyone in the audience who was shooting P2 or SxS to raise their hands if they "backed up" on hard drives. About 95% raised their hands.

I told them to leave their hands up and then, anyone who HADN'T had data loss to har drive failure to lower their hands.

No one did. I asked if anyone saw a dichotomy with those two facts.

Right now with current technology, DLT, SDLT, and LTO are the only reliable methods of long term archiving I would rely on for paying clients.

Its what your bank records are backed up on.

IF you "back up" your data on hard drives, please do yourself a favor and get an assistant or intern to regularly write and read data to every sector of the drive using a disk utility.

If you don't, then one day you may find that your data is no longer there.
 
mcgeedigital, care to elaborate on what DLT, SDLT, and LTO is?

EDIT: Just did some googling, the recorders are pretty expensive but seem like the right way of doing things.
 
To each their own. You have to weigh the costs with both the benefits and risks.

If it works for you and your work flow then that is all that matters.
 
i think i will change from LTO 1 to LTO 3. However what backup software is the best to use for LTO 3 ??? I can't find anything that will run on XP. They all seem to run on win 2003 server and cost upwards of £500 just for the software!!

Windows XP pro has a backup program that i use for LTO 1 but is a really bad bit of software. It can’t even tell you how much space is left on a tape or what is on a tape !!!

What backup software are broadcasters or production companies using for LTO.
There must be an industry standard.
 
Someone needs bring out an LTO Video backup program that editors can use to back up projects and video footage.

It would be very useful if it had a CMS so clips could be easily found.
 
As per Barry. Review Ultrium LTO4 tape drives (Quantum, IBM, TAndberg, HP etc). THe interfaces are SAS, FC and SCSI. I have a quantum ULTRIUM4 LTO4 tape drive desktop model SAS interface. CArd is an ATTO EXRESSSAS R380 (any will do).

Quantum Ultrium4 LTO TApe drive is $USD2600+ from http://www.digitape.com - they sell outside usa.

Software is TOLISGROUP BRU LE - soon to be replaced with BRU PE when available. (http://www.tolisgroup.com)

Ultrium4 get you abut 92MB/sec from SAS interface. Constricted a little by the source or target DISK file system. Best to read and write from disk array with large blocksizes.

TApe cartridges run from $USd65-$usd80 depending where you get them. capacity is 800GB uncompressed. SO that's 800mins of DVCPROHD 1080 I suspect.

For a small business MAM, check out CATDV. The guys at UBC2008 said they have an interface to TOLISGROUP BRU.. looking at this now.

P2 archives using ULTRUM LTO4 --

There are several OSX based workflows around. For the single or small usr, look at TOLISGROUP's BRU LE (soon for BRU PE (Producers Edition). http://www.tolisgroup.com

This is all OSX based. (suggest to forget retrospect and others.. these seem to have lost their way over the last 10 years).

NO need for external server. TAPE drives connected directly to OSX host via SAS, FC or SCSI and for ULTRIUM 3 tape drives from QUANTUM can be over ETHERNET (not my favourite). BRU LE/PE is priced well and works first time on a single MACPRO. i beleive there are some PCI-X-SAS cards around so in that case maybe also working for the MACBOOKPRO. I dunno.

Select OSX HBA's carefully - ATTO and LSI are a good start. FC Ultrium tap drives will connect on HBAs over FC. I use the SAS interface model (desktop).

Also as per previous post, look at a MAM system that is OSX based call CATDV (http://www.squarebox.co.uk/). It was demo'ed at IBC2008 this past week. THe cost is £157 (pounds).

lots and lots of detail here for MACPRO + ULTRIUM LTO4 SAS tape drives + HBA that work on  MACOSX with data TAPE + OSX Software (Archive.app) that works on MACPRO natively including several other links to other forums where this detail is. -

refer http://www.dvxuser.com/V6/showthread.php?t=114778&page=2

and all the links there includes details of working configs that work immediately.
