Does anyone know of any software for the ibm-pc/xt/at (DOS) that will allow true incremental backups over a tcp-ip network ? We currently have several pcs connected via tcp-ip (Excelan EXOS-8052) with various vaxs and sun workstations. We want to be able to backup the pcs to a tape drive on one of the vaxs. I know that I can do it brute force by copying over files with ftp/ftpd and then writing them to tape, but what we really need is true incrementals (backup all files modified since xx-xxx-xxx), preferably with as little operator intervention as possible. Even some tcp-ip routine librarys would help so that we could write something ourselves, but I haven't seen anything like that for DOS. Any help would be greatly appreciated. Please respond via mail, decvax!cg-d!finan. Thanks Tim Finan Compugraphic Corp. Wilmington, Ma. decvax!cg-d!finan

Regarding a question about true incremental backups for any MS-DOS machine, are there any backup programs which will actually delete files or directories off of the initial backup, when these have been deleted off the main fixed disk? Not an answer to the original question of Tim Finan (finan@cg-d) regarding automated backups off of networks, but how intelligent are any of the backup programs available for MS-DOS machines? --Mike Volow, Psychiatry, Durham Veterans Administration Medical Center Durham, NC, 27712 919 383 3563 mvolo@ecsvax.UUCP

I hope some one has one real soon ( a program for doing an incremental backup of PC files over the LAN to a UNIX machine with a tape drive ), as it will save me a lot of time and trouble. If not, I will have one ( my plans call for me to begin creating such a program towards the end of March if I have not located one ). Currently I am performing incremental LAN backup of over 80 UNIX systems nightly ( each system uses the find command with -mtime since the beginning of the week, accumulating a list which the backup machine then grabs over the LAN and uses in saving the files to tape, by cycling through the list of each machine saving the files specified ). We are currently adding about 3 dozen HP Vectras ( AT-compatabiles ) to the LAN, and will be using FTP Software's LAN programs for telnet, ftp, and mail ( we are ordering their tcp-ip programming libraries to help in custom program creation ). But they don't include ( and I can't find anyone who has ) any facility for doing backup's over the LAN. Sooo... The current plan is to write a program that will run on the Vectra at logout ( or at night with an "alarm clock" interrupt ) that will go through the file system looking either at the archive bit or date to determine which files to save, and then ftp those files over the LAN to a UNIX machine ( to a separate directory for each PC ? ) which will then save the files to tape. This will probably be written quite easily and quickly ? in Turbo Pascal. So if someone doesn't come up with one before me...

One possible solution to your problem is PC-NFS from Sun. It will
allow you to use the DOS BACKUP utiltiy (I know, yecch) to do a
disk to disk backup to the "other" disk which is really the hard
disk on a UNIX machine. You may want to put some of your
frequently used software on that disk to clear out the local
disks.
Warning(s): there is a performance hit from using NFS as opposed
to local disk, your clones may not supports the hardware, and
some software may not be legally used over a network.
