Re: using large hard disk as backup desitination
If you back up to a "Macintosh Disk" rather than a "Macintosh File", does the 2 GB limit still apply? (This prevents you using the drive for anything else however) If not, you could partition your big HD down into 2 GB chunks. Then Retrospect should parcel the "Retrospect Data" file among them as needed, right? -- top of the world, Luke Jaeger, Technology Coordinator Disney Magazine Publishing Northampton, Massachusetts [EMAIL PROTECTED] Any opinions expressed in this message are my own and may not represent the opinions of Disney Publishing, etc etc etc. * -- -- To subscribe:[EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED] Archives:http://list.working-dogs.com/lists/retro-talk/ Problems?: [EMAIL PROTECTED]
Re: using large hard disk as backup desitination
no no, this could work. If you could get Retro to treat a bunch of disk images as if they were 2G removables, it would stripe the backup data across as many of them as it needed. The backup would not be limited to 2G. The disk images would be like multiple tapes (zips, cdr's, etc) in a storage set. Backup set. Whatever it's called now. This is probably easier than my original idea of separate 2G partitions. Wade Masshardt wrote: RE: You can use resedit to make retrospect recognize other media. I back up to disk images all the time. Ask tech support for the fix or if you can't get it I have it archived away somewhere. Tom In this case it doesn't gain me anything, really, since the disk images have the same 2GB size limitation. If DiskCopy is able to create larger images in the future, I'll hunt up the fix, so thanks for the info. -- +--+--+ |Wade Masshardt| The Wisconsin Alumni Association | | Tech Support Coordinator | 1-888-WIS-ALUM (1-888-947-2586) | | 608-265-8766 |http://www.uwalumni.com/| +--+--+ | mailto:[EMAIL PROTECTED] | +-+ -- -- To subscribe:[EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED] Archives:http://list.working-dogs.com/lists/retro-talk/ Problems?: [EMAIL PROTECTED] -- top of the world, Luke Jaeger, Technology Coordinator Disney Magazine Publishing Northampton, Massachusetts [EMAIL PROTECTED] Any opinions expressed in this message are my own and may not represent the opinions of Disney Publishing, etc etc etc. * -- -- To subscribe:[EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED] Archives:http://list.working-dogs.com/lists/retro-talk/ Problems?: [EMAIL PROTECTED]
RE: using large hard disk as backup desitination
Reply to: RE: using large hard disk as backup desitination Michael, I'm really not sure why this was done. I'm assuming it was decided to wait until Apple lifted the 2GB limit before working around it in the software. Now that Apple has lifted the limit, that's our cue to change Retrospect's capabilities... I'll be sure to flag this suggestion, though.

Now that Apple has lifted that limit, we need to change Retrospect to reflect that new capability. We'll probably be doing this in our next release. I understand that the physical file can't exceed 2GB (at least prior to OS9), but I don't understand why this is a barrier to doing a file backup set that exceeds 2GB in total. Other programs are able create segmented files when they reach a given size. If I'm reading the message that Eric posted to the list a few months back (see below) correctly, even your own program understands how to do segmentation when dealing with removable media. So my question is, why can't it do segmentation (via containers or whatever) when dealing with a file backup set on a fixed drive that exceeds the 2GB mark? Barring some technical reason, maybe that option can be added to the next update (ideally where the user can set the segmentation size)? This has benefit of working even for those of us that choose not to upgrade to OS9. It also provides a mechanism for dealing with the issue when we start to reach OS9's file size limits. Although at 2TB hopefully we wont reach that point for a year or two. :) Thanks At 3:15 PM -0700 8/19/1999, Eric Ullman wrote: With Retrospect 4.1, we included support for filling removable cartridges that hold more than 2GB, by writing multiple containers as required, up to the media's max storage capacity. However, we can't do this with file StorageSets (on a second hard drive, for example); one must use a duplicate (OS format, no compression) operation to fill a 9GB hard disk.

using large hard disk as backup desitination
In order to speed up the backup during the week (it is taking 12-14 hours to back our site up to our Travan 5 drive), I hit upon the idea of buying a Promax Ultra ATA DMA/33 PCI card and a 25 gig IBM deskstar drive (total cost about $475 including delivery) and using that as the backup destination during the week. After I get this all set up, I find out that Retrospect's file backup set has a limit of 2 GB, which seems a little restrictive to me. I need about 14-20 gigs worth, so is there any way, other than making a bunch of 2 GB file backup sets and adding them all as destinations, to use the whole disk as a backup destination? If anyone from Retrospect is reading this, is it possible to up the file backup set limit to, e.g., 2 TB, now that the Mac filesystem supports files that large? -- -- +--+--+ |Wade Masshardt| The Wisconsin Alumni Association | | Tech Support Coordinator | 1-888-WIS-ALUM (1-888-947-2586) | | 608-265-8766 |http://www.uwalumni.com/| +--+--+ | mailto:[EMAIL PROTECTED] | +-+ -- -- To subscribe:[EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED] Archives:http://list.working-dogs.com/lists/retro-talk/ Problems?: [EMAIL PROTECTED]

Now that Apple has lifted that limit, we need to change Retrospect to reflect that new capability. We'll probably be doing this in our next release. That will be great. Any idea when this release might be forthcoming? In the meantime, the method described, namely using a bunch of file backup sets (11 in my case) as the destination for a backup should work, right? My main concern (I haven't actually tried it yet, tonight is the first night) is that Retrospect will automatically move on to the next file backup set when the first one is full and so one (I have about 14 gigs worth of data that gets backed up when I do a recycle backup.) If this is what happens, then everything should be peachy. If not, I'll have to find an alternative, like making 11 2GB Diskcopy images and using those as the target.
