backup and logs

[Dimitri Papadopoulos-Orfanos <pa...@shfj.cea.fr>]

Hi,

I'm moving from Perforce to Subversion and I'm having trouble 
understanding how to implement backups, specifically in connection with 
logs.

With Perforce, the repository ("depot") and the logs ("journal") 
typically live on separate disks. If the repository disk fails, you 
restore the repository from the latest "checkpoint" available from 
backup, then use the journals accumulated since the "checkpoint" - still 
available on the other disk.

With Subversion, the repository and logs live in the same directory. 
Therefore it looks like Subversion logs cannot be used to restore the 
repository from the latest available "hot copy" in case of disk failure, 
since both the repository and the logs would be lost.

For backup purposes, are Subversion's "incremental dumps" the equivalent 
of Perforce's "journals"? That's what I understand from the Subversion book:
