Re: Macintosh File
Good Morning Eric, Thanks for the clarification. I had given some thought to storing "short term" archival copies of the large backup set files on an ASIP Server we use to store disk images of CD-ROM's. Glad to know it's not so simple. I think a second large ATA drive on our "Backup Machine" is the way to go. Having the most recent three months of work backed up to a Hard Drive, being able to restore without inserting a tape, is the kind of magic the folks I support like. Hi Tom, It's actually the AppleShare IP server software that doesn't support files larger than 2 GB, even with Mac OS 9.0.4 and a Mac OS Extended formatted disk (HFS+). The workaround of formatting an ASIP volume as "removable" will allow Retrospect to create 2 GB file backup sets until the volume is full. Your 14 GB file backup set would not be allowed on an ASIP server. HTH.

I'm either on a different planet or not understanding this exchange. I have been using Retrospect 4.3 to backup 6 Macintosh Graphics Workstations to a 40GB ATA Drive on a BW G3 since October 1st.

While this method is supplemented with a VXA Tape Drive for off-site and archival copies, the speed and simplicity of backing up to and restoring from a large Hard Drive has been wonderful the past few months. The only way to do this is to format the entire volume as a removable cartridge. Retrospect will then fill it with separate 2 GB container files. You'll need formatting software other than Apple's Drive Setup. DANTZ DOES NOT RECOMMEND OR SUPPORT THIS WORKAROUND. Eric Ullman Dantz Development [EMAIL PROTECTED] wrote: Try partitioning the drive into segments 2GB, and then define all of the partitions within Retrospect as members of the backup set. If my assumptions about the way Retrospect works are correct, then it will fill up each one in turn and the files will not get over the 2GB limit imposed by ASIP. As I said, I haven't tried this, so it's really a guess. Does anyone see any reason why this wouldn't work?

If so, you may have other problems. But you might try compressing it with Stuffit Deluxe, and dividing the resulting compressed file into parts. (Though if the 2GB limit is set by the OS then this probably won't work either.) At 12:16 PM -0600 on 12/15/00, Donovan Brooke wrote: Thanks Eric for your help. I didn't think of looking towards ASIP as being the problem, but it looks to be just that. Realizing now that a single file can only be a max of 2 gigs, is there a procedure for spliting up the file to back up onto? Can retrospect jump to a new file when it has reached 2 gigs or can I designate another file to copy to when it reaches the 2 gig limit??? - Thanks, - Donovan Eric Ullman wrote: According to Apple's Tech Info Library article #15460, "AppleShare File Sharing: Chart of All Limitations," last modified 11/17/2000, ASIP 6.x still has a 2GB file size limit. http://til.info.apple.com/techinfo.nsf/artnum/n15460 -- -- To subscribe:[EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED] Archives:http://list.working-dogs.com/lists/retro-talk/ For urgent issues, please contact Dantz technical support directly at [EMAIL PROTECTED] or 925.253.3050. -- Thomas D.

VXA Tape Drive, Error -24201
Just received a new Ecrix VXA-1 Tape Drive . Attached it via suppled cable to Apple Macintosh BW G3 using stock Apple (Adaptec) 2940U2B LVD SCSI PCI card (only external device attached on this card). Tape Drive is terminated with supplied terminator. Using Retrospect 4.3, Test Backups with verification work just fine, no errors. Testing the Restore function yields the following error message:" Sorry, restore preparation failed, error-24201 (chunk checksum didn't match)" Retrospect recently upgraded from 4.1 to 4.3. No problems backing up to or restoring from existing DDS-2 DAT Drive (on different SCSI card). Researching the problem on the Dantz Website reveals the following: -24201 (chunk checksum failed) One of Retrospect's files, likely a catalog, is corrupt. To check whether a catalog is corrupt, set up a restore by searching on a blank file name so Retrospect scans all files in the catalog. If the error occurs, you know this catalog is corrupt. If the error occurs during a backup or archive, you need to rebuild the catalog (page 189 of the Retrospect User's Guide) of the destination. After the catalog is reconstructed, reselect this backup set in your scripts. I have tried recreating the catalog from the tape, it seems to complete this task successfully, but a Restore attempt yields the same error message. I have also tried reinstalling Retrospect and the error remains the same. I haven't found any further information on the Ecrix or Dantz Websites. Please help me solve this problem. -- Thomas D.
