Missing backups from Catalog

[Nerdling]

Hi Guys,

I've been asked to run a restore for an Exchange server in out environment.  I fired up the BAR utility and set the Backup machines and Polict type with the following variables:

         Server for backups and restores:
         Backup01

         Source client for restores:
         Mail

         Policy Type:
         MS Exchange

I have backups from now to mid August 2012 then nothing until December 2009.

If I change the BAR paramters to the phisical nodes:

         Server for backups and restores:
         Backup01

         Source client for restores:
         Mail01

         Policy Type:
         MS Exchange

I have backups from now to mid August 2012 then nothing until December 2009.

         Server for backups and restores:
         Backup01

         Source client for restores:
         Mail02

         Policy Type:
         MS Exchange

I get an error indicating that there are no backups.

Is this becasue the environment is clustered?

[mph999]

Nothing to do with the cluster.

Goto this dir ...

/usr/openv/netbacklup/db/images/<client name>

or

<install>\veritas\netbackup\db\images\<client> (if windows)

There should be some directories ... example

1334000000

1335000000

1336000000

Please list up here what dirs you have.

Regards,

Martin

Try this command :

 bpimagelist -d 09/01/2012 -pt MS-Exchange-Server -U

if this command return a list replace -U with -L to see more details. The command searches the Netbackup catalog for Exchange backup made since 09/01/2012.

[Mark_Solutions]

Have you recently upgraded your system?

Just wondering if you were using an altpath for the exchange servers to re-direct their backups and some catalog files are elsewhere that are not being picked up - you may need to locate them and copy them all back to the default location

Hope this helps

I ran the command from 09/01/2011 to see what I got.  Looks like there is still the hole.

We have recently upgraded from 7.0 to 7.1.

We did not change the default settings during the backup and I checked our catalog after the upgrade and everything looked to be in order.  If I were to go looking for image files, what extension should I scan for?

[mph999]

As you can see, these dirs contain the backp header / and 'files' file.

For example the 1334000000 dir will contain backup info for anu backup that has a backupid  starting 1334.

A new dir is created every milllion seconds, if a backup id run.

The rules are ...

The dir is only created if a back runs in the time period it would cover.  If no backup runs the dir is not created.

If a dir is created and hold backup image info, if these backups are expired, the dir is never deleted.

1/

From this, we can conclude that if a dir is 'missing' either the dir was created else where (eg a symbolic link couold have been created).

2/

The backups never ran in that time period

3/ 

The dir was manually deleted with OS commands.

One thing I can confirm, is once the dir is created, it is impossible for NBU to delete it, it does not have this ability in the code. ( You can probably tell I have been 'here' before ... just a few times).

If you want to look for the files, try searching for files ending in ...

_INCR

_INCR.f

_FULL

_FULL.f

... that should cover it.

Even if you have the files elsewhere, we may still have a major issue.

NBU knows where the image catalog is .../netbackup/db/images

When it runs a cleanup (every 12 hrs by default) it checks that for any media in the media DB (which means it should contain images) it can find it in the image database.  If it is not there, the tape is expired ... no ifs, no buts ....

So ... the bad news, if the images are in a different location, AND, no other images using the same media exist in the 'live' DB area, they will have been expired.

(This by the way, is by design, if the images are not there, NBU cleans up the tapes).

Martin

(ps. It works fine providing you never play a game  of 'hide your catalog' (or bits of it ...))

Take a look at the policy - What schedules do you have along with their retensions (please post)?

08/07/2012 you have 4 infinity backup. After that point the backup seems to live 35 days before expering them.
