Re: Advice requested: tape system

I am therefore looking for an economical, reliable tape based solution that
can handle the job.

I've read discussions about using IDE drives.  You can get 40 GB 
drives for around $200.  At that price, you can get five drives, use 
one to write your backups to and then swap it out replacing it with 
the next hard drive.  I imagine that on Windoze you could even 
arrange for them to be hot swap-able.  I imagine it would be pretty 
fast, too.

Re: Retro Speed

2000-09-05 Thread Keepsake

I apologize for reopening a dead thread on the list, but I just 
wanted to share.

Running Retrospect 4.2 on a Quadra 950 with 40 MB RAM over built-in 
ethernet to our ASIP server, I get 13-16 MB/min.

Having moved Retrospect and the tape drive over to the server* (after 
addressing stability concerns) and upgrading to 4.3, I get 25-40 
MB/min.

*PowerMac 9500/132
Using Seagate Travan tape drive (using byte-by-byte confirmation for safety)
Tape drive connected to external built-in SCSI interface
Initio Miles 40 MB/sec SCSI card
7200 RPM Atlas III drives

I wish I could get anywhere near this, mine tops out of about 40Mb/min even
an a G4, mind you it's only a 2606 SCSI card with DDS3 drives, even with
built-in SCSI on a 7300 I don't get above 40. :(

In theory I should be getting 60Mb/min coming from our old NT server as I
can get 1Mb/sec copying from it.

Re: freezes in Mac while backing up....

2000-08-17 Thread Keepsake

Andrew Stein said:
The backup run of any script ( or any backup attempt at all) will 
freeze at a random point during execution, with the software running 
and the tape drive read light off, and remain so forever.  If the 
system is loaded without extensions, everything works fine, the 
script run perfectly.

I have seen this kind of problems when I had one or more files with 
corrupted resource forks on the ASIP server.  It would choke either 
at the time of backing up the corrupted file or shortly after the 
backup completed.  Check with DiskWarrior and/or Norton Utilities to 
locate any such files and then either trash the outright or try to 
repair them by opening them up with ResEdit (usually doesn't work).

Brad Suinn, ASIP enginner, has posted a file to his iDisk that has a 
number of recommendations for making your server most stable (user 
name "Suinn").  It is quite worth the read.  It has a section with 
regards to Retrospect.

Re: Linux Client

2000-08-17 Thread Keepsake

GF requested:
Hey Dantz, when will a Linux client be available? Obviously you are working
on one...

Of course, the current workaround is to have SMB or Netatalk running 
on your Linux/Un*x box so its volumes can be mounted on the backup 
server and backed up.

 Being that OS X has a rather incestuous relationship with NetBSD, and

Actually, it is FreeBSD that Apple has utilized for OS X:

Of course, I believe a reasonably bright programmer could create a 
cross Un*x platform solution, so it really would just be one product 
for Linix/BSD. I know if I get my way to set up an OpenBSD server, 
I'd love to have Retrospect backing it up.
