Hi Paul, the subfile cache doesn't hold the whole file, it holds signatures of some sort, probably a checksum for each page. I use subfile for pst files. My pst is 75 meg but the folder is 5 meg.
We went thru a conversion to outlook 2 years ago. First, you're lucky to be involved before the conversion is done. The key is the attachments. If the conversion from the old mail client can leave the attachments out of the pst then you will have much smaller pst files. Unfortunately we loaded the attachments in. As I said, I wasn't asked about the conversion until it was done. Also, there are programs which extract attachments from the pst. We use EzDetach. It helped a lot but the deployment of it wasn't completed so we have lots of psts > 2gig, some up to 10 gig. Yes, they backup every night. I made a special management class for them with separate disk and tape pool. The tapes cycle faster because expiration deletes everything from them. Good luck!

I didn't realize the cache directory was limited in size and that it held complete copies of files. Checking this, it seems you may be correct about full copies of files being made in the cache directory. The size of the cache directory is only 1GB according to the Users Guide, and that is what the EditPreferences GUI restricts you to as well.... I don't understand how subfile backup can work for files up to 2GB in size, if the subfilecachesize is restricted to 1024 MB. >In short, you can only manage a total of about 2 GB of files for subfile >backup, and only files less than 2 GB in size are eligible. Bummer. Thanks Wanda. ..Paul -- Paul Zarnowski Ph: 607-255-4757 Manager, Storage Services Fx: 607-255-8521 719 Rhodes Hall, Ithaca, NY 14853-3801 Em: [EMAIL PROTECTED]
