How to backup P2

[flaminio]

I just put in an order for more FW800 drives from Otherworld. Basically I back everything up in pairs. Unless something physically happens to the drives, the odds of two failures seems quite remote. Two 1.5T drives work out to $0.37 per GB, which seems reasonable. In total, I'll have 7 TB of external storage, plus 3 TB internal. This should keep me working for the time being.

Next year I'll probably look into a LTO4 drive + SCSI card. 800 GB capacity and ~800 GB/hr works for me. It's just a pricey unit.

Another option is I'm getting a Sony PDW-U1 drive to ingest XDCAM, but even if I buy the 50 GB disks, that's too small to be worth the effort, plus they're pretty expensive and probably won't come down much. Bluray is another option, but same story except media will likely come down in price.

The way I figure, is I can use my HDD solution for current and recent projects, and also a staging area for backup/archive. Maybe once a quarter do the chore of transferring to tape and clearing out drives.

I need long term backup. I do not need to access the footage.

in that case you really want to examin the economies of ULTRIUM LTO data tape. There's tonnes of posts on this in eth REDUSER.NET forums.

Some posted in these forums.

THE TCO of a small ULTRIUM LTO4 system (or cheaper and less fat and fast is LTO3 ULTRIUM) =

• HP ULTRIUM SAS LTO4 desktop tape drive $USD2700 (inital cost. ULTRIUM3 is cheaper but may need to do SCSI not SAS. THIS config on OSX MACPRO WORK EXTREMELY WELL!>
• ATTOTECH EXPRESSSAS H380 (host buss adapater only) - $USd100's ??
• Archive / backup sofwtare for MAC OSX .app single user = TOLISGROUPS BRUPE/LE .. a couple of $$usd100's depending where u get it and from whom.
• several ULTRIUM LTO4 tape media (800GBnative) around $USd49 or less in ots of 10's. (much chepaer for LTO3 media but you get 50% of LTO4 Ultrium).. cant see the value myself of using only LTO3 ultrium.

Simply once you have set up this initial cost, you can expand this archive into 100's of TERRABYTEs over a long time without buying anymore el cheapo disk.

I doubt there is a very good cost efective argument for long tie archive these days. Cheap SATA disk are not the long term answer (whether in FW, SATA or USB enclosures).

Good DDms are SAS or SCSI and these cost heaps more that the same capacity DDms in SATAII interfaces.

IMO: Look at the recent issues in the press about the 1,5TB Seagate BArra's .. its getting much harder to get a 2TB disk wi the sam efoot print and price as its recent 1TB SATA2 disk.. BArras had one of teh best names for DDms...

IT is well know that DISKs should stay spinning and that his constant spinning generates the HEAT that is a stable tempreature. When powering a disk down , it obviously cools a bit , some shrinkage (yep! for sure) and then powering it up agan like this will help if fail. So as an archive media for LONG TERM they are rather unreliable as my experince has been over many years - expecially with someway irreplaceble compositions and footage. (where I lost it over two events witth two Le CIE FW 1TB elcheapo disk).

As someposts in this and other forums, people have enjoyed sucess with DISK arhives. I'd say they have been foryunate. I'd like to see what happens in 5 years whenthey want that contet back again.

Even using some DVD;s I first used for archive in my old 2001 TI MAC POWERBOOK cant be read at all on this MACPRO.. beats me..


look at DATA TAPE for LONG TERM until somethng else comes aong.

FWIW
