[comp.sys.mac.hardware] Backing up servers in a Mac/Sun network

francis@giza.cis.ohio-state.edu (RD Francis) (07/26/90)

I'm looking for helpful suggestions as to my back-up options.  We've
got a few hundred Macs, and a few hundred Suns, Suns on Ethernet, Macs
connected in by several Fastpaths.  I'm looking for a way to back up
my Mac servers (data being most important -- I can reconstruct the
server folder simply enough) using our existing equipment.  The
possibilities that I am presently aware of would include:

1)  Dumping the contents of the servers to a Unix box through ftp or
through AppleShare (oh, yeah, we've got three Gator boxes and are
running KIP, plus at least part of CAP).

2)  Directly accessing the Exabyte tape drives?

3)  Getting A/UX and using it to copy Mac volumes to a tape somehow?

I'm not sure if any of this makes sense; would my best bet be to
suggest getting NetStream/JetStream, and handling things that way?  Or
is there some relatively simple way to get tape back-ups onto our Unix
machines?

Heck, i'm willing to suggest Network Diskfit and a Syquest cartridge
hard drive.  Right now, I'd just like to know what you people out
there are doing to back up your 80+ meg HD's, especially if you use a
connected Unix network in the process.

Thanks in advance.

You can get some information about Mac backup software from the July 1989
issue of MacUser.

I'm working on a similar problem.  We have a half dozen Macintoshes
that I'd like to back up to a UNIX machine.  Right now I'm considering
using Redux to backup the Mac files via AUFS to the UNIX machines.

Redux and DiskFit both have the advantage of being "imaging".  That is, they
maintain an "image" of the Mac's hard disk.  Since our UNIX machines are
backed up nightly, there is no need to keep a complete chronology of the
changes to the files in the backup.  

But, neither Redux nor Network Diskfit handle AUFS terribly well.  Neither
one can do incremental backups over AUFS.  Since Redux allows more control
in choosing which files to backup, it is leading in the consideration.

Coupled with QuicKeys/QuickTimer, I can trigger the backup late at night
or via a single key combination.

I'd also appreciate any info others may have on this subject.

Here is one scenario:

Hardware configuration:
A network of UNIX boxes with their own backup system (eventually
everything ends up on tape), and a set of Macs connected to the
internet (in our case directly through ethernet cards, but KIPs or
Gatorboxes should do just as well). The macs have large harddisks (300 MByte).

Backup configuration:
One UNIX box runs CAP, and functions as an AppleShare server.
Designate one directory on the UNIX box as a backup volume, and let
the Macs that are going to be backed up mount it.
Install RetroSpect, an archiving/backup program. RetroSpect will
automatically initiate backups at the intervals I choose (daily for
documents, weekly for programs and the system folder). RetroSpect
will back up to the AppleShare backup volume, and the UNIX backup
system will move it onto tape whenever appropriate.

RetroSpect is a wonderful program - it does full backups,
incrementals, selective on almost any criteria you may wish for, and
automatically (e.g. at 2AM when I am not at work).

Best of luck,

Sigurd Meldal
