In my backups, the Current is always the first backups and the =
incremental is the new version of the files that are in the Current. =
Which means that if i restore the Current backups, I won't have the last =
versions of the files. Wouln't it be more interesting if the Current =
backups were always the last versions of every files, and in the =
incremental, the old versions of theses files (with no file if there are =
no change on the files...)
To make things clearer, I have for example in the current backup a file:
file1.exe 10 may 2003

and in incremental
file1.exe 12 may 2003
file1.exe 15 may 2003

Why don't we have instead this :

Current:=20
File1.exe 15 may 2003

Incremental:

file1.exe 10 may 2003
file1.exe 12 may 2003

Which would make the CURRENT backup always the LAST versions, and in =
incremental, the past versions of the files. The reason behind this is =
if one day one of my servers crash and i want to restore all the files =
by copying the Current folder to the new server, i dont want to =
overwrite after all the files with the incremental files... i should =
only have to copy the current files, and in case i need an older file, i =
can have a look in the incremental files...
What do you think about this?

Best Regards.
