Hi Jaume
old backup. The file was 2.4GB in size and it did the rsync only
transfering 140MB. It's still alot of data, but it's not bad.
What I don't understand is that changing the blocksize to the same
size as the pagesize gave me the best result? Does gbak backup data i
chuncks equal to the pagesize of the database?
Why is it unuseful? The database contaings PNG/JPG images, which is
already compressed. I would never be able to compress the file to
140MB!
Why is it dangerous?

> How efficient it will be is just another thingYesterday I tried backing up my database and rsyncing it with a 8 days
old backup. The file was 2.4GB in size and it did the rsync only
transfering 140MB. It's still alot of data, but it's not bad.
