Backing up original DV tape data for archival purposes

I have >50 hours of unedited family video on original source DV tapes. I want to duplicate the data on the tapes so if the original tape is lost or corrupted, I'll have a backup. I've been looking at options that have a shelf-life on the order of decades for archival purposes.
Someday I may be able to afford a Blu-ray disc burner and (Delkin) gold archival BD-R discs, but while I wait for prices to drop the most economical way seems to make duplicate DV tapes.
I have two questions:
Question 1: Is there a way to make a duplicate DV tape using FCE and a single DV camera (e.g. print to tape) or dubbing using two cameras without using FCE? If so, how, and which way is best?
Question 2: The original DV tapes contain data that indicates the date and time the video was originally shot. Is it possible to preserve this date/time data when making a backup DV tape?
Thanks for your help.
Footnote --> For other people looking for ways to archive their video data, gold archival CD-R and DVD-R discs are available (e.g. MAM-A or Delkin) but their capacity is rather small and IMHO would require an inconveniently large number of them to store many hours of original video data. Blu-ray is still rather pricey and Delkin seems to be the only manufacturer of archival gold BD-R discs so far (BTW, they advertise 200-year life span; I've seen no details of their testing process for BD-R media). I've also investigated the longevity of data on hard disks and hard disks are unsuitable for safely archiving data for tens of years or longer. Magneto-optical discs are reliable but this format seems to have fallen out of favor. While magnetic tape is susceptible to EMI and other environmental risks, it is very economical.

It's easiest to dub between two DV cameras. Get a 4-pin to 4-pin FireWire cable and connect the two.
You have to test the second. It's dependent on the device. Most likely not. BTW, that information is not preserved in FCE.

When changing appointment on outlook after time they back on original time and date

I have user that when makes a change to a meeting and sends the update to the recipients, they get the new meeting request and it updates on their calendar with the correct time and date. Then for
a brief time or past day the senders calendar will show the change then disappear and the original time and date pop back up again on all users get the meeting.
Time zone on all pc's same, date/hour correctly.
All with windows 7 + Outlook 2010 (+ sp1, full update).
I have Exchange 2013
any help and tips will be appreciate
Thank's

Hi Rdanny,
Do you mean both Organizer and Participants' meeting back on original time and date?
Does the Organizer give others delegation permission?
Does this issue always occur or just once?
How about changing time in OWA? If you didn't try it, please try to change the meeting time in OWA for testing.
If in OWA, this issue disappeared, it seems an issue on the Outlook client side.
I suggest run Outlook under safe mode to avoid some AVs and add-ins.
I suggest try to re-create the Organizer's profile to refresh the caches.
Also try to check whether there is any related error message in the App Log.
Thanks

Since loading Lion I can no longer burn photos form iPhoto on a dvd for archive purposes

Since loading Lion on my MacBook Pro, I can no longer burn photos form iphoto for archarving purposes. I used to load the dvd and it would showup on the screen then drag highlighted photos onto the dvd. Now, dvd only shows up sometimes and when it does, it tells me the new disk is full. How can such an easy task become obsolete with this update. I have also tried using idvd for archiving purposes but this process will only allow viewing. I want to be able to reload photos back onto the computer at a later date.

I habe the same problem and cant find a helpful post on the web!
How can i get it back to work???

Highest compression for archive purposes

Hey Everyone,
I'm looking to compress my videos at very high quality for storage using compressor. (some of my videos are 1-2 minutes others are 5 minutes). I tried a couple of times but my exports were 20 gb...too large.
In case I ever put together a demo reel or something, i'd like for my archives to be at the highest quality with the minimum space being taked up. Any thoughts?
Thanks!

Many institutions use MPEG-2 at very high data rates for archival or mezzanine storage. You can do this in Compressor. Create a custom MPEG-2 setting; set the stream usage to Generic; and then crank the bitrate up as high as you want to go...with the understanding that the higher the bitrate the better the quality, but the larger the file size. If you move the slider all the way up to 40 for SD material you can get around 3 minutes per gig.
You can then choose Program Stream in the extras tab and YUV encoding (Compressor 3.5) for higher quality muxed files.

ProRes versions of VHS tapes for archival purposes

I need to create archival digital copies of some aging VHS tapes. I have a sony mini-dv deck that I used with iMovie as a passthrough for my VHS deck. Final Cut Pro X won't let me import the footage without the timecode. I know other people have had the same issue and they end up using iMovie but I haven't seen a solution that will allow me to import the video Pro Res quality. Any ideas?
Thanks,
Kara

I recently archived about 400 hrs of original VHN footage shot back in 1985-95 era. Majority of them were captured directly via s-video cable and rca audio. The codec I used was DV25 and few DV50. Pro Res is quite overkill for VHS. The format is a mere 240 lines. Quite outdated to today's 1080p TV standards. Used FCP 7 and no tc needed. When comes to edit, switched to FCP X.
When you're doing DV on any deck, you're adding another layer of hardware decode and encode. DV has a 5:1 compression ratio w/ 4:1:1 sampling. It's not the best intermediate format. I'd try to minimize anything via DV and get it directly by using real time hardware. But this needs a decent capture card to do the job right the first time.
But for Betacam SP w/ analog component, I did capture via DV50 and Pro Res std. That should preserve ther analog 4:2:2 Beta SP tape formats.

Best encoder for archival purposes?

I have been using AAC with 256 resolution recently for all my CD imports to iTunes but I occasionally get skips in the songs (happens on all computers). So two fold question.
1) Am I better off using MP3 with Constant Bitrate of 256 or higher for best quality for importing and archiving to iTunes, and
2) What causes the skipping of imported CDs even when the originals play just fine in other applications or CD players?
Steve

archival is a tricky word. it implies you want to keep the files in as close to original as possible. for true archival quality, you could use the apple lossless format, but its not practical at all.
VBR is the best comprimise, it just sorts out the difficult to compress areas and gives them a higher bitrate than the rest of the file. i just set it as 192kbps with VBR, which is what i used with MP3, i figure the MP4 AAC LC encoder in itunes has improved since its early days, (not all that confident though it doesnt matter too much)
however, in your case, i think that the 'ripping' engine in itunes is the problem.
if the gaps and pauses are in the middle of tracks, then it is the drive correcting data incorrectly by using the ECC values from the cd/dvd drive to smooth over the invalid areas. try switching it off, it might help, but it depends on the drive and the CD in question.
it's been a problem in the past for most removable media, reading errors and correcting them has 2 approaches, guessing what is supposed to be there by using the error correcting codes (faster, default behaviour) or re-reading the data several times at low speed until the same data is read back (slower, can damage hardware by constantly spinning up and down to re-read the same sectors).
if the gaps are only near the end and beginning of tracks, then it's more likely due to the encoder and/or the disc. but ts uncommon, encoders are pretty good these days.
some copy protection methods break the mastering conventions (known as red-book CD audio) so you'd probably need to read the disc at 1x speed instead of 30x to 40x as you normally would. even then, it might not work OK.
there are worse forms of copy-protection, most are oriented towards disabling or slowing down 'ripping' across the entire CD's content.
if you have windows, getting a hold of EAC to rip the files is the preferred fix.
or, get a 1:1 cd copy program (i.e. programs used to rip copy-protected games will also rip copy-protected audio CD's) such as blindwrite or clonecd, which will allow you to make a backup from a damaged/copy-protected disc. you can then mount the disc image in a virtual cdrom and test that the virtual image is error-free.
you can also use slysoft's anyDVD to have an on-the-fly application that repairs copy-protected media i.e. dvd's and audio cd's with copy-protection for personal use. it also makes reading dvd's and cd's faster and less hardware intensive.
for mac, well, there's umm ... bootcamp. a regular toast/dmg creator won't do the job if its one of the nastier copy protection mechanisms, they damage/alter the error correcting data on the disc intentionally so that the drive itself mangles the data every time it grabs that section of the cd.
programs like EAC just read the data in it's raw form over and over then compare each pass for integrity. if the drive is passing the mangled data to the OS and correcting it on the fly (via ECC), then your drive just wont be able to read the audio cd's without those gaps and breaks.
so, in short, it's been a problem for a while.

Best practice for having separate clone data for development purposes?

Hi
I am on a hosted Apex environment
I have a workspace containing two instances/ copies of the application: DEV and PROD
I would like to be able to develop functionality and data in/ with the DEV instance and then insert it into DEV.
I gather that I can insert pages from DEV to PROD via Create -> New page as copy -> Page in another application
But I don't know how I can mimic this process with database objects, eg. if I want to create a new table or manipulate the data in an existing table in a DEV environment before implementing in a PROD environment.
Ideally this would be done in such a way that minimises changing table names etc when elevating pages from DEV to PROD.
Would it be possible to create a clone schema that could contain the same tables (with the same names) as PROD?
Any tips, best practices appreciated :)
Thanks

Hi,
ideally you should have a little more separation between your dev and prod environments. At the minimum you should have separate workspaces each addressing separate schemas. Apex can be a little difficult if you want to move individual Apex application objects, such as pages, between applications (a much requested improvement), but this can be overcome by exporting and importing the whole application. You should also have some form of version control/backup of export files.
As far as database objects go, tables etc, if you have tns access to your hosted environment, then you can use SQL Developer to develop, maintain and synchronize between your development and production schemas and objects in the different environments should have identical names. If you don't have that access, then you can use the Apex SQL Workshop features, but these are a little more cumbersome than a tool like SQL Developer. Once again, scripts for creating and upgrading your database schemas should be kept under some sort of version control.
All of this is supposing your hosting solution allows more than one workspace and schema, if not you may have to incur the cost of a second environment. One other option would be to do your development locally in an instance of Oracle XE, ensuring you don't have any version conflicts between the different database object features and the Apex version.
I hope this helps.

Collecting media for archival purposes

does anyone know about a way to collect all the media in a DVD Studio Pro Project? We have many, many projects, but the media used are across several hard discs - now to burn the projects including it's media on DVDs it would be great to have a collecting media function such as in InDesign - does that exist? Any suggestions???
Mac OS X (10.4.8)

There is no internal mechanism, such as in InDesign or Final Cut Pro, in DVD SP to gather assets like that -take a look here for some thoughts on project management in general

Advice for keeping high quality files for archiving

I'm contemplating archiving here. I love reference files because they are pretty small in file size and don't compress. However, I have to worry that all my files will remain in the same exact place forever. I have found that is not always the case for whatever reason. Then there is self-contained reference files. A great idea...I don't have to worry about moved files but the file size is enormous. I do long videos (sometimes an hour or so) so file size is really important to me.
Is there anyway I can do a self-contained reference file but somehow reduce the file size or something? I know I'm throwing a bone here but I figured I would ask because my current scenario is not improving daily. I know I can put my hour or whatever to tape but that essentially is compressing it and I'm using valuable time. Any advice?

HI Lowsky, I been down this road some time back and my opinion is that if you are working in any workflows associated with CMFs (contemporary media format) in a tapeless workflow then storing your LONG TERM content as CMF's on spinning disk will eventually lead to misery and a hopeless state of anger and heartache. Spinning disk is not the long term answer.
refer here for lots of detail: I have post this detail in another forum at
http://www.reduser.net/forum/showthread.php?t=21284&page=6
*Archiving FCP Media Manager Projects, essence, import/transfer material.. etc*
Aside from many testimonials about DISK being faster (more accessible?) and convenient, storing content on spinning disk is a like as a child having all the toys you could imagine but only playing with your 3-4 favourites. (replace with any analogy). Simply you only need the stuff around on disk that you actually use a lot or currently.
I (and I'm not alone) don't trust and disk storage system unless you buy enterprise level disk arrays with some fault tolerance and smart disk array controllers AND that you have at least multiple instances of the content. I qualify ENTERPRISE disk systems - these at $USD5.00-$USD10.00/GB+. I mean those disk arrays from I,T. vendors, and M&E guys like Isolon, DDN, Apple, HP, Copan and their 40+ ilk.
The affordable stuff most of us is around $USD0.25-$USD0.75/GB - SATA and lowest end HBA's or simple controllers. Basically just spinning +power soaking heat dissipating buckets+ to put our content into. (USB | FW or the external JBOD disk enclosues with an HBA or higher FC disk arrays)
Most of these are enterprise disk storage systems that are out of the price range of many on this forum...
Devices like DROBO™ are cute but they are way way too slow (29MB/s when not busy consolidating itself ) and are very limited on their architecture for VIDEO work (useless). I gave mine away after a week to a photographer.
Alternatives like many sets of external and detachable and mobile spinning disks, leaving them spun down until use offer a great odea however unless the disk controller is savvy, you may as well have a bank of el cheapo Le Cie 1TB death disks and get on your knees and face the moon when you power them up.. (Good = luck with that!) mode=:rant
*Viable Archive Solutions for CMFs?*
After looking for viable solutions to by content storage problem after moving to a tapeless workflow with my HVX200 and P2, AND losing on two separate occasions a whole 1TB external disk (Le Cie).. losing most of the data of two drives (2 x 1TB over 4 months).. I have had it with disks!
For me, Disk storage should only be used like a +kitchen table+ for immediate and current and frequently accessed work. Like the +toy analogy+, hen not in use, put the toys away somewhere where they will not be damaged (the content objects) (like a large toy box or cupboard) that you can access with ease. (not the garden shed out the back nor the attic else it will never be used). This is workflow is simple enough..
My first thought for managing FCP media manager archives, P2 footage and final composites was to use BD's.. however the cost for the content that was wanted to archive was not cost effective. I had literally 100's of old video tapes, DV , HDV and ye old video8 rubbish that I needed to move to a CMF, all accessible via proxies and metadata (a la CATDV™ a mam from squarebox.co.uk). The restriction was COST of BD or DVD-DL media and worse the time of write and then access the material ESSENCE when I needed it.
I even looked for a while at many 100's of DVD-5's which in Hong Kong are as cheap as free beer coasters in a bar. I would buy them in canisters of 100's at a time. Simply these are cost effective using TOAST to make multivolumes self extracting archives, but are SOOOooooo slow to write and then access.
So I turned to looking at the economies and workflows of using LTO4 Ultrium data tape drive. I was quite surprised at the reasonable cost.
The cost of Ultrium LTO4 data tape media of to 800GB native for prices that are as cheap as $USD1.40/GB as pure media (the tape cartridge itself).It depend where you buy them and at what quantity. Of course there are the necessary offset/initial costs of the data tape drive AND the SAS HBA you will need for your mac. (LTO4 Ultrium @ $USD2700 and $USD150+ for SAS HBA). Much cheaper fo Ultrium LTO3 but lower data rates and capacities.
NExt year HP et al will have Ultrium LTO5 out at 1.5TB RAW/native capacity as their roadmap suggests.
THe uncompressed / RAW data rates of LTO4 Ultrium data tape drives for ARCHIVING material is for me between 105MB-109MB/sec (that's megabytes).. simply BLOWS any firewire 800 interface out of the water. There are many variables however essentially for people like us whose business is content creation or even the part timer who doesn't want to lose stuff, this is really worth a look. Again it will depend on the software you utilise. I use Tolisgroups BRU.
Just do the sums on the time it takes you to archive (or copy to another disk system [BD or DVD-5, DVD 9, et or a spindle) lets say 4 hours of DVCPROHD 1080P (110Mbs or just over 1GB/minute). You can see that this is a lot of content and will take a great deal of time.
This works out at roughly 240GB.
I think this will take over 500 minutes (6 hours? @ 2min/GB)+ to COPY on a FW400 interface and slightly less on a FW800 interface.
However it takes a mere 2200 second or 36 minutes using an LTO4 SAS Ultrium tape drive (with no tape mount/dismount timeloadlocate)!
On a lesser scale, a look at DDS tapes for the low end. These are despite rumours/myths are quite stable and work well with the right software on the mac and the mac laptop.
I am having great success with this archive and recall system using Tolisgroups BRU that is NATIVE for OSX.
I have posted some very recent information on the two SAS PCIe HBAs I am using (ATTOTECH and LSI) and the two tape drives I am using (HP and QUantum).
For LTO4 Ultrium SAS tape drives I would recommend only HP and ATTOTECH EXPRESSSAS as this is reliable and very stable and very fast for OSX.
I am very happy with this archive/recall workflow using LTO4 Ultrium data tape for FCP.

How to find photos with no original or digitized date?

I have probably 500-1000 photos that have neither Original or Digitized Date info. They are scattered all throughout my iPhoto library (30,000). They do have Modified and Imported Dates; but of course, not only do those dates differ (sometimes substantially) from when the photo was taken, iPhoto seems to use the Modified Date for sorting purposes if the Original Date isn't there. That means these "dateless" photos are way out of sequence when View, Sort Photos is set to By Date.
What I need is some way to easily find these photos. I can't set the date search feature to a "null" value, nor can I create a smart album that filters for a null date value. If I slowly scroll through all my photos and watch the numbers carefully, I can usually see which photos have no Original Date because they're out of sequence, but with 30,000 photos, that's going to take forever.
Does anyone know any tricks or third-party software for this?
Thanks!

If a file doesn't have an EXIF date then the file created/modified date is used by iPhoto. Files that have been scanned or optimized for web use fall into that category.
The demo version ofMedia Expression can catalog an iPhoto library and then with a search for Date is after 1/1/84 you will find all files with an EXIF date. After applying a label to all found you can display all files without a label which would be your files. How you would then identify those so that they can be found in iPhoto I don't know. Any keywords you might add or other metadata would not be recognized by iPhoto unless they were reimported. If you are interested in trying that post back and I can give you a workflow. It would involve creating a new library and importing the Originals folder of the old library after you run Expression Media on it to embed the keywords (those from iPhoto and those you add to the dateless files), titles and comments to the files. It can be done but might be a bit involved.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

Using a single Content server for DMS and also for Archive link documents

Hi,
We have Planned for a single content server for managing the documents in DMS, parallelly as DMS Standard SAP objects are not available for all SAP transactions, i have proposed for making use of SAP Archivelink funtionality to maintain the documentations where Std SAP DMS does not provide a Solution.
so here the question is
can a single content server be used as a content repository for Both DMS and archivelink,
can any one having done this pls state if it is possible to create different or Many Content repositories for DMS, Archive link in the same server,
is this a virtual creation or can we assign each repository a specific storage space which it should not exceed.
Thanks and regards
Sathish

Hi sathish,
-- Through the ArchiveLink docuemnt Management interface, an SAP sytem can use various content servers as storage media. similarly, one contnent server can be used by multiple SAP systems.
-- A Content server always has a single database assigned to it. A database can therefore be used by only one content server.
-- A databse is split into as many repositories as necessary. The design of the repository is mapped in the SAP system.A repository contains documents.
Depending on your requirements,(if u have limited documents or with low requirements) you can use the same content server for both DMS and Archivelink.
The number of documents stored on the content server is limited only by the size of the database.
Its better to have an external content server for archiving purpose, if your database size is increasing. Since the archiving systems storage is not dependent on the database.
U can also refer to the below thread :
How to Archive SAP DMS Data?
hope this helps....

Delete DSO data for current month on a daily basis.

Hi Gurus,
We have a requirement where we have to delete the data in the BW DSO's for the Current Month every day before loading data into it. The reason for this is that in R3 they delete data for the current month in addition to adding new records and changing existing records. Since we do a Full load in BW, the deleted records in R3 will still exist in the BW DSO, hence the need for deletion.
We can't delete ALL the data in the DSO as we use the BW DSO for Archiving purpose and the R3 table at any point of time will have just 3 months of data, while BW will have historical data.
I know there is a process to delete DSO contents in the Process Chain, but can it be set up to just delete the current months data??
Thanks
Arvind

Hi Arvind,
The program RSDRD_DELETE_FACTS or transaction DELETE_FACTS will help you in deleting the records. Execute the program and select the option 'Generate Selection Program'. It will create a Z program , you can then dynamically select the current month in the Variant and assign the Z program and the variant in ABAP step of the process chain.
Hope this helps with your requirement.
