Use of Blu Ray for data back on server

[JMP]

Greetings! I am looking for information regarding the capability of using the Blu Ray technology to backup our servers. Could someone be so kind as to point me in the right direction? With regards, Joe

a dule layer burning drive is a good start.

then some soft ware that backs up only thing im sure that dose is nero
for that u will need main software:

Roxio 9 will also backup to BD.

I ran a commercial information systems shop for 17 years and I'd say that Blu-Ray may make sense for you IF you can backup your entire production dataset on one 50GB volume in the time available. Based on my own BD-RE backups (MyPictures=43gigs) that will take close to four hours. My firm ran shop floor datacollection 24/7 and I believed any backup that ran more than an hour, even if it was in background, was too long. We used 4mm DAT tape at the time.

If I were doing it now I would back up to an SATA disc in an enclosure over shielded eSATA cable and have 7 enclosures in rotation + one a month for 12 more datapoints. Based on the eSATA drive I use to archive my .m2t files, that same 50GB would take 23 minutes. A full terrabyte on a nice new drive would take 8 hours. If you ever had to recover from these, it would be much faster too ... at a time when the entire world would be beating down on your head!

By the way , if you need an instaneous snapshot for a backup, you can try a technique I considered then. Lets say you keep your active dataset on a mirror pair (RAID1) AND your mirror/resynch software can be driven by a script. You write one that at the appointed moment desynches the mirror pair, mountes the released copy, backs up on the the media of choice and then resynchs when done. Now it matters less quite much how long the backup takes. You do want to be done with the resynch before the next day's activity gets hot and heavy.

This would be Ideal for a small mom and pop shop that isnt working in the Multimedia industry. Your RTO would be off the charts if you wanted to do this in a mainstream data shop. Most people are leveraging some sort of Copy on first write technology like Volume Shadow Services. That way you can get instant snapshots and build out synthetic fulls for backups. Stage that backup to cheap disk then archive to tape. But even todays Tape Technology will outdrive a single disk. The fastest FC disk sustains around 170 IOPS and Ultrium is aproaching 300 IOPS.

uh. what?

Apparently the idea I posted just above for "instaneaous snapshots" has been implemented in XP already as "volume shadow services"...........
