>>> Also, QIC-80 drives don't hold enough to make frequent backups very attractive (too much tape swapping).<<< I know what you mean about QIC-80. I hate almost everything about them, except price. The slow speed and whining is annoying. I finally bought a HP 1533 DAT. Totally opposite of QIC-80, superfast (33MB/min), silent, and it holds 4-8+GB. I backed up a 400 frame animation in under 6 minutes. Well worth the price in just time savings, swapping, tape cost. A 4-8GB DAT tape @ $20 compares to 4GB QIC-80 tapes @ $320 and 8GB QIC-80 tapes @ $720. The price of the tape media offsets the price of the drive.

>> I finally bought a HP 1533 DAT << I've been using a SONY SDT-5000 4mm DAT drive for about a month. I think it uses the same DDS-2 tape as your drive. I can back up the PAR drive directly, but have to go through my SCSI DOS disk for restore. Are you able to restore directly to PAR? What about the dreaded frame >896 problem? (I am not experiencing it). Also, I am using Corel SCSI-2 and their backup program, which is pretty limited. Do you have any suggestions for a good backup program — I have been trying to get some info on NovaBack from NovaStor. Thanks! Cal

>>> I've been using a SONY SDT-5000 4mm DAT drive for about a month. I think it uses the same DDS-2 tape as your drive.<<< Yep, the Sony SDT-5000, WangDAT 3400X, and HP C1533 are all DDS-2. The tapes SHOULD be interchangable as far as data transfer goes. >>>I can back up the PAR drive directly, but have to go through my SCSI DOS disk for restore. Are you able to restore directly to PAR? What about the dreaded frame >896 problem? (I am not experiencing it).<<< My PAR arrives tomorrow (yipee!), but I hope I avoid the problems a few people seem to be having. I heard problems with certain firmware versions on the 2217A, though I don't know which versions work. I just got the 2217A today. My hardware is Dell XPS P90 w/32MB RAM #9 Imagine 128 video 1GB EIDE HD Adaptec 2940 SCSI NEC 4Xi CD-ROM HP C1533 DAT Plus the PAR and TBC IV. >>>Also, I am using Corel SCSI-2 and their backup program, which is pretty limited. Do you have any suggestions for a good backup program — I have been trying to get some info on NovaBack from NovaStor.<<< My Adaptec 2940 came with Backup Basics which is a stripped down version of Backup Exec for Windows, seems to be OK. I have Norton Backup for DOS, but I haven't checked to see if it supports the HP DAT, I used it with a QIC-80 previously. I will be adding a 2GB Seagate Barracuda in a few weeks and removing the EIDE drive. So I hope to be backing up from PAR->DAT, and back. I'll let you know if I have any problems with SCSI. I've seen NovaBack, but haven't any info on it. I'm looking for DOS, Windows, and OS/2-Warp backup programs. I'm going hunting for them after the holidays, I'll post results. I'm also looking to get a program like Tape Store which treats your DAT drive like a hard drive. With the fast 30 second access for a file on DAT a sequential read/write of animation frames should be simple. I have used that type of program on the Amiga and it worked great. Maybe that will allow people to avoid backing up the PAR to tape since it will think the DAT is a HD.

Is this Tape Store a DOS program? Could it be used in a Video Post batch file to backup the just rendered frame to tape? Bob

>>This sounds really interesting. Is this Tape Store a DOS program?

So copying files is simple. It will allow straight DOS copies, but is quicker if you run a special copy program that they supply. Works like a charm and should solve all of the problems mentioned in this thread.

Suresh: >> I have a program called TapeDisk that treats most SCSI tape drives as a DOS disk << Could you tell me where you got TapeDisk? The manufacturer's name, maybe a phone number? Have you used it with a PAR system? Thanks! Cal

Tapedisk is authored by: Tapedisk corporation. 1-414-231-3333. It supports most SCSI tapedrives including the Exabyte 8500 as well as quite a few DAT drives.

Have you used this software for doing system backups? Is it compatible with most backup software? It seems like using a 10Gig DAT for backup purposes would be the way to go for truely _unatended_ backup!!
#144697From: Suresh KavanJan 2, 1995 10:08 PM
Yes. Yes and Yes. I use a 5 Gig Exabyte drive… I prefer not to use tapedisk when doing a full system backup because when you use a dedicated backup system like COREL's or CENTRAL POINT..it saves the files as one huge 'thing'. DAT's and Tapes are real slow at moving around so throwing the data at it in one go is better. For video storage..as a kind of off-line / on-line massive storage mechanism, tapedisk is superb.

Suresh: TapeDisk sounds like what I'm after. Thanks for the info, I'll track it down. Bob

See my other reply for the tel #. Hope it works out for you. SK.

Cal: /__________________From your message___________________\\ Are you able to restore directly to PAR? What about the dreaded frame >896 problem? (I am not experiencing it). ________________________________________________________ I dream of the >896 problem as I seem to be the only one languishing with a >128 problem. I have no animation that will survive a backup/resotre if its longer than only 128 frames. This really sucks! Although I thought your message was a scorcher I might be compelled to add fuel to your fire shortly. I would just just like to hear DPS say that they were trying to help us out here EVEN IF IT ISN'T THEIR PROBLEM. It concerns the usability of their product and it would just be good business, IMHO, to identify the cause. Bob

>> I have no animation that will survive a backup/resotre if its longer than only 128 frames << Curiouser and Curiouser… I havn't had a chance to experiment with v1.30 drivers. I'm using 1.09 currently. What are you using? Cal
#142777From: Christophe Van OyenDec 20, 1994 5:13 AM
Do you have the backup problem with 1.09??? BTW in PAL we seem to start at 1.29 and then 1.33 but with all versions we seem to have the problem althugh with 1.29 woe also had another problem PRJ deletion. This seems to be solved with 1.33 however, my PAR backup problem really is eating me away, it is such an anoying problem. Christophe
#142932From: Cal HainesDec 20, 1994 9:14 PM
Christophe: I don't remember how you responded to this question, so I'll ask it again: Does the problem exist if you use the DOS command line COPY command to move files back and forth to the PAR drive, that is, outside of PAR.EXE? I loaded the PAR 1.30b drivers and tried 1,100 frame copies both ways, no problems. Cal

Cal: I appreciate your effort. Looks like our collective voice has been heard (Thanks to Brick for letting us know that DPS is helping out on this one). The only major difference I see in our configurations is that I use QEMM vs EMM386. Bob

Bob: >> The only major difference I see in our configurations is that I use QEMM vs EMM386 << I don't have QEMM or I'de give it a try it. Maybe you could try EMM386? Are you on a Gateway 2000 / SCSI platform then? Have a Gamma Fine Christmas! Cal
#142847From: ROBERT RITGERDec 20, 1994 11:54 AM
Cal: I am using v1.30b but have tried restoring animations with v1.09 and have had the same problem at the same place. 7*128 = 898. There was mention that the problem occurs on frame numbers which are multiples of 128. Bob
#142933From: Cal HainesDec 20, 1994 9:15 PM
Bob: >> I am using v1.30b but have tried restoring animations with v1.09 and have had the same problem at the same place. << I assume that's the case using both PAR.EXE and the DOS command line? I have NOT had the problem from DOS using the PAR drivers from PAR v1.09 or v1.30b, nor have I had the problem with PAR.EXE v1.09. I tried using PAR.EXE v1.30b and I get the following message: Fatal Error 286.2230, Load Program Failed — out of memory from the 286 Pharlap extender. This is also true with the v1.27b drivers. I have 625k of base memory free prior to loading the PAR drivers, 590k free after, as well as 29Mb of XMS memory. I couldn't free up any more memory if I had to. This is the first time I have tried v1.27 or v1.30b up on this machine, a P5-90 — didn't have the problem on a P5-60 with identical memory, drives, etc.. Any ideas? I'd like to try to replicate the problem. I feel kind of left out, what with everyone else having corrupted file problems… Cal

Cal: /_______________________From your message________________________\\ I assume that's the case using both PAR.EXE and the DOS command line? __________________________________________________________________ I have only copied .ANI files back to the PAR with a DOS command. I'll check my available memory but I know I am no where near your 590k free of conventional memory. Bob
#142776From: Christophe Van OyenDec 20, 1994 5:10 AM
strange I've only never been able to restore >896 never had any problem so far with >128 When are they going to fix this problem so we could all live happily ever after with our PAR??? Christophe
