Stripeset File (10 MByte) addon of Basebackup
delete *.chg
if a Stripeset of 10 *.chg Files exist, they should be converted or merged
to one bigger *.rsf Stripesetfile (to prevent for having Millions *.chg)
Why? What does this actually do?
This is the Structure on FTP-Site of the Backupserver! Not locally where
the Postmaster runs on!
Locally the Postmaster can create a basebackup (rcvry.rcv) then the
FTP-Deamon logs on to the
Remote FTP-Backupserver and Uploads this File to keep it save:
/pg/backup/12_24_2008/
/pg/backup/12_24_2008/base/rcvry.rcv <--- Basebackup
At the Next:
If a New Record at the Database was written, then the Postmaster locally
creates
A change File named: "0001.chg"
After thits the locally FTP-Deamon transfers this File to
/pg/backup/12_24_2008/changes/0001.chg <--- Changed Data
Then
/pg/backup/12_24_2008/changes/0002.chg <--- Changed Data
/pg/backup/12_24_2008/changes/0003.chg <--- Changed Data
....
/pg/backup/12_24_2008/changes/0010.chg <--- Changed Data
Then the FTP-Backupdeamon merged the last 10.x *.chg Files to one greater
*.RSF File "Online while logged into the FTP-Backupserver" and Delete Online
the Last 10 *.chg Files (after this the Last 10.x *.chg Files, created
by the Postmaster
can be deleted localy where the Postmaster runs).
The Benefit:
If the Machine where the Database run on having a Mailfunction, then the
Last Record
of the Databasecatalouge is backed up to an *.chg or *. RSF File.
Thadt my Idea of this
