Every night I run a db2bak.
Can this backup be safely restored to a different server? using bak2db?

If it is a configuration server (having NetscapeRoot in db),
it cannot
be, unfortunately. And of course, the base suffix (or
suffixes) should
be identical between the 2 servers.

I have tried this before without luck. I was hoping there was a way. My situation is I have nightly db2bak files. I want to recover the database from friday to a different machine to see the state of the application then. I do not need much other then read only access to the old data on the new server.
Any crafty hacks would be appreciated.

It won't.
I had to do a restore by necessity, and here's what I had to
do (by
Noriko Hosoi's gracious recommendation):
1. on the current directory server, export the data into
ldif files.
go to your <server_root>/slapd-<id>; run
"db2ldif -n <backend>" for each backend
(e.g., userRoot) EXCEPT NetscapeRoot
2. install new FDS
3. go to the <new_server_root>/slapd-<id>
4. stop the directory server
5. import the ldif files from the current directory server
repeat "ldif2db -n <backend> -i
<server_root>/slapd-<id>/<date_time>.ldif&
quot; for each <date_time>.ldif file exported in (1).
6. start the directory server
The issue is documented in this thread:
https://www.redhat.com/archive
s/fedora-directory-users/2007-February/msg00024.html
The NetscapeRoot instance is server-specific, and it won't
restore
properly on a new server.

Write a script that runs "db2ldif -n
<backend>" for each backend (e.g.,
userRoot) EXCEPT NetscapeRoot
On the new server, import the ldif files generated above:
"ldif2db -n
<backend>"

Unfortunately I only have the db2bak from the day I need to restore. No ldif files. And I need to restore them to a new server. I do not need all the configuration data. I only need two of our data trees.

OK, I found a stragegy that worked.
I took vmware and prepared a virtual machine. I did the RPM install of the same directory server 1.0.4. that was installed on the old server. Luckily I had retrospect on the machine. I used restrospect to do a full disk restore of the old system onto the new one.
I stopped networking on the server first for fear that the system would start up and try to join the live systme and corrupt data.
The server did startup but the data was not as it was that day. This was probably due to the fact that retrospect backed up open files of the FDS.
That is ok though. I also had been running db2bak every night. I used back2db.pl to restore one of the backups over the current. Then I ran db2ldif and moved the ldif files out. Then I did an rpm -e fedora.1.0.4.
Then I reinstalled FDS again and used the ldif to restore the data.
The long way around. Having VMWare was nice because I was able to shut down networking but still access the VMWARE console from the network.
