ciskokid 0 Posted March 7, 2012 Hi Folks Scenario 750 Cameras recording at 12FPS/CIF for 24hrs per day for 180 days 15 Cameras recording at 24FPS/4CIF for 24hrs per day for 180 days Both H.264 Now I have been asked to investigate rather than standard NVR (RAIDS etc) could we use a tape system for the following reasons – ‘potential alternative storage solution involving tape storage rather than hard drive or solid state. The tape storage providing higher security for CCTV images from virus’s and cyber attacks.” Feel free to ridicule should you wish. Thanks Jimmy G Share this post Link to post Share on other sites

hardwired 0 Posted March 7, 2012 (edited) Quick calculations I did show needing four DAT drives with 160GB tapes, to get to one tape change per day, per drive. So, average cost I found on DAT160 tapes= $37 USD X 4 tapes per day, X 180 days = $26,640 USD (plus the drives @ $600 USD each)= $29,040 USD. So, it just depends if the cost for a solution like that is worth it for you (keep in mind, you would need someone onsite changing tapes every day, as well). ******Edit***** Wait, that's wrong, I'm still working on this.....

ssmith10pn 0 Posted March 8, 2012 ‘potential alternative storage solution involving tape storage rather than hard drive or solid state.

I service EMC equipment in data centers every day and some companies such as Kaiser Permanente have multiple large tape storage arrays. I'm not talking old outdated crap... State of the art robotic storage arrays the size of a small uhaul. Share this post Link to post Share on other sites

survtech 0 Posted March 8, 2012 We looked at backing up our evidence clips to tape a few years ago. We also had a vendor trying to convince us to buy a hybrid storage system that would store on RAID for a short period, then on tape for the remainder of our required retention time (7-60 days, depending on the camera). We concluded it wasn't worth the cost and hassle of tape drives and libraries. In my mind, tape is a step backwards for both live storage and clip archiving. The cost to record live to tape is high and ready availability of recordings is low so we looked at other options and decided to keep the live data on RAID but switched from RAID5 to RAID6 for safety. Since then we have not lost any live data. For evidence storage, we bought some WD MyBook RAID Edition external USB drives and back up the clips to them on a regular schedule. Cheap, fast and still capable of being stored off-site. Share this post Link to post Share on other sites
dustmop 0 Posted March 9, 2012 I use tape, but that's for backup of incidents that are kept on a RAID-6 box. Full backup every few months, incremental backup every few days. Automated 24-tape LTO-3 library. Takes about 18 LTO-3 tapes for a full backup. Wish I could switch to LTO-5, but I can't justify the price. In reality, you could duplicate your entire storage system for what would ultimately be less than tape, if you consider labor costs. A monster SAN might be a bit pricey, but you could look into things like EMC or Pivot3. Both have experience in the surveillance world, too. (and no, I do not use either product) If security of said video data is of a super high priority, put it on it's own physically separate network. Do not let it touch any other network at all, whether in-house or the internet. If you must connect it out, do it through a nice ASA, and lock it down tight.

dustmop 0 Posted March 12, 2012 Full backup every few months, incremental backup every few days. How long are you keeping video? If it was turned into an "incident" where it was specifically clipped for whatever reason, we keep it forever. All of that video is stored on one large RAID6 array (~10TB), and then backed up to tape like I said above. At the current rate of use, that box will be full by this time next year.

ssmith10pn 0 Posted March 12, 2012 I'm just curious what type of environment requires over a year of storage. Not to mention once it's archived to tape it has to be a real pain to retrieve. Share this post Link to post Share on other sites
ssmith10pn 0 Posted March 12, 2012 Also, what type of "Incident" wouldn't fit on a DVD or thumb drive? I have one customer considering doing all of their incident recordings on SD cards. They are getting cheap and will fit in a paper file nicely. Share this post Link to post Share on other sites
dustmop 0 Posted March 12, 2012 Every incident ever saved is on the array. It is backed up to tape for disaster recovery. We've been saving incidents for several years now, and we don't like to destroy old records. You never know when you'll need something that might mitigate an insanely large lawsuit from a few years ago. I work in a bit of niche market, however, and the way we do things is most commonly seen in city centers/government/casinos. Some of the incidents might contain dozens of hours of footage. Also, when you submit evidence to lawyers/LEOs, it has to be on a CD/DVD, along with the md5 hashes and watermarks, so they can show it wasn't tampered with. They would never accept something on a thumbdrive, as any good defense attorney would destroy the credibility of the evidence on said device based on that fact that it simple COULD have been tampered with.
