From what I understand about synthetics, you have to have one real full
backup, so there has to be a schedule with that type.
Just run another non-synthetic full backup if all you want is a full

It's NTFS and you're creating and deleting a lot of files on the volume so
of course it will fragment. Either defragment the volume or set the minimum
threshold lower so that more files get deleted when the cleanup process runs
to reduce the fragmentation.

Today's NTFS handles fragmentation alot better - in fact, FAT and FAT32
were really the main file systems that would always get fragmented. That
is not to say NTFS is not immune to the fragmentation that people may
experience, but there are ways around to minimise it even more.
Depending on the
I still think that MS's undelete feature plays a part in this. When
data is deleted in Windows, NTFS marks blocks to be released without
actually erasing them. Rather than reusing released blocks, NTFS
prefers new, unused blocks, which leads to fragmentation.

H Not sure its common in NTFS though, however the older file
systems FAT FAT32 definetely would play a part in this.
Saying that, if users continually delete files from the same volume and
they are restored from tape, would this increase fragmentation?
I'm curious if the image fragment size has any impact on file system
fragmentation?
I have used 2gb for disk staging on vxfs/solaris successfully, but I
never got the DSU volume much past 80% full.

You need to run a differential and then a synthetic full immediately
following. The synthetic basically takes your last full and applies all
the differentials to it to create a new full image.
Full + Diff + Diff + Diff = Synthetic Full
Synthetic Full + Diff + Diff + Diff = Synthetic Full

I run the synthetic fulls each week, so 9 days gives me the overlap I

Hi Jamie,
Read this:
*LTO-4* can *read*/write LTO-3 tapes but can only *read* LTO-2 tapes. It
cannot *read LTO-1* tapes

As to TOP's question, have you tried running a full, then a series of
incrementals, THEN a syn full or cumulative incremental? That's what
it's designed for. Why would you make a syn full from a full? The
results would be the same a duplication of that same backup, with a lot
more work. The

Is *.ldf and *.mdf the correct way to exclude all mdf and ldf files,
regardless of what drive they are on? Or, do I need to specify the drive
letter for each drive the ldf and mdf files reside on (D:\*.ldf,
E:\*.ldf)? The admin
Hi all,
Does BMR really speed up recovery significantly? Reading through the
documentation it seems that between the multiple reboots, reinstalling windows,
restoring the data files, reformat time, it seems like it doesn't save much
time over a typical restore (manually reformat the system,
*.ldf and *.mdf is all you need. NetBackup will exclude every
occurrence of files with those extensions even if you offer it cash to
take them.
Thanks,
Randy

I would say yes, it is worth it. A few extra seconds on the backup job
to collect BMR data, a BMR server for each of your supported platforms,
and you get a simple way to get all your data back along with the
configuration. I too witnessed a moderately complex windows system come
back to life
I've always said NetBackup can do anything you want it to do and it will
do exactly what you tell it to do. That's good and bad. Symantec
should merge with Google that way when I execute the wrong command,
NetBackup will give me a popup with Did you mean . . .
