Hi All,
I have two classes backing up overlapping data on several Windows 2000
Servers. One goes to a tape drive/robot with a long retention time and the
other to a local hard drive with short a retention time.
For Example:
Class = WinDataDisk
File List = C:\, D:\, E:\
Schedule = FULL, run Weekly, retain 2 weeks
Schedule = INCR, run Daily, retain 1 week
Class = WinDataTape
File List = C:\, D:\, F:\
Schedule = FULL, run Weekly, retain 3 months
Schedule = CINCR, run every 3 Days, retain 2 months
Schedule = INCR, run daily, retain 1 month
I have turned off the Perform Incrementals Based on Archive Bit setting on
the client.
The question is will NetBackup do the incrementals for WinDataTape based on
backups that ran for WinDataDisk of solely based on WinDataTape.
Tanks for your help.
Andre

On page 478 of the NetBackup DataCenter System Administrator s Guide -
Windows NT/2000 (page 516 of the PDF) it says
Determining Files Due for Backup
Windows NT/2000 Clients On Windows NT/2000 clients, NetBackup performs
incremental backups of files based on the Perform Incrementals Based on
Archive Bit setting in the NetBackup Configuration dialog box. To open this
dialog box, start the client-user interface on the client, click Configure on
the Actions menu, and go to the General tab. If the Perform incrementals
based on archive bit box is checked, incrementals for this client are based
on the state of each file s archive bit. The operating system sets the bit
whenever a file is changed and it remains set until cleared by NetBackup. The
conditions under which NetBackup clears the bit, depends on the type of
backup being performed. u For a full backup, NetBackup backs up files
regardless of the state of their archive bit. After a full backup, the
archive bit is always cleared. u For a differential-incremental backup,
NetBackup backs up files that have the archive bit set and have therefore
been changed. When the client receives a response from the server indicating
that the backup was successful (or partially successful) the archive bits are
cleared. This allows the next differential incremental to back up only files
that have changed since the previous full or differential-incremental backup.
u For a cumulative-incremental backup, NetBackup backs up files that have the
archive bit set, but does not clear the archive bits after the backup. This
allows the next cumulative incremental to back up not only changed files, but
also files that were in this cumulative incremental. If the Perform
Incrementals Based on Archive Bit box is clear, NetBackup includes a file in
an incremental backup only if the file's datetime stamp has been changed
since the last backup. The datetime stamp indicates when the file was last
backed up. u For a full backup, NetBackup backs up files regardless of the
datetime stamp. u For a differential-incremental backup, NetBackup compares
the file's datetime stamp against the last full or incremental backup. u For
a cumulative-incremental backup, NetBackup compares the file's datetime stamp
against the last full backup. If you install or copy files from another
computer, the new files retain the datetime stamp of the originals. If the
original date is before the last backup date on this computer, then the new
files are not be backed up until the next full backup.
