Morning,
 
Happy to report that first MSSQL 700MB database dump across ADSL took 433
mins to complete and resulted in a 130MB compressed file, but the night's
first full backup took 22mins to sync the changes!
 
A few things, then I'll leave you all in peace for a while (maybe!):
 
1) Spot-checking backups:
 
  Any in-built or documented way to generate or view the MD5 hash of a
backed-up file so that files in a backup set can be spot-checked against the
MD5 of the original?
   -- if not, would be a nice feature to be able to click a button or link
to ask the for hash of a file - I presume this would have to trigger a
temporary un-compress and MD5 generation procedure
 
2) The FAQ states "Rsync running on Cygwin is limited to either 2GB or 4GB
file sizes". 

    Does this still hold true (page last modified in 2006) - I am concerned
because our database dumps are going to grow!
 
3) I have a very sturdy Dell PowerEdge 1300 - a dual PIII-450 box - that
*could* be a backup server, but am I expecting too much for the horsepower?
This box would sit on a remote site and backup around 10 servers via ADSL
VPNs

Thanks again - have to say that based on feedback so far you are a friendly
bunch! Hope I can contribute to the project in some way.

Nigel
