rfutil MARK BACKEDUP does not work for incremental probkup
Customers can choose to use a system utility (ex: tar, cpio, etc.) or
procopy instead of probkup when backing up their databases. However,
if they do so, then they can not get incremental backups with probkup.
This is true even if the database is marked as having been backed up
with the rfutil -C MARK BACKEDUP command. The MARK BACKEDUP command
is to be used only with After Imaging.
If a full probkup is not done before an incremental probkup is taken,
the first incremental probkup will take a full backup of the database.
This is because the first incremental will backup all changes since
the full backup and since there was no full backup, will backup the
entire database. This is true for both v6 and v7.
Example 1: Full probkup followed by incremental probkup
1) probkup demo demo.bkup
2) update database
3) probkup demo demo.incbkup incremental
4) demo.incbkup will only contain changes since step 1.
Example 2: rfutil mark backedup followed by incremental probkup
1) procopy demo2 demo2.bkup
2) rfutil demo2 -C mark backedup
3) update database
4) probkup demo2 demo2.incbkup incremental
5) demo2.incbkup will be a full backup
