Hi Christo,
there was a mail this monday describing the problem in detail.
Here the answer from Leslie in this mail.

Your problem restoring is probably because Netview uses the sparse
filesystem. So, while you may backup using tar, you should use the pax
command to restore. This way the restore will not take more space than
the original data did. The syntax is:
pax -rp e -f <tarfile>
Using this command you should be able to restore the large database
that contains your cut/paste work.
Then you should probably consider switching to the turbo form of the
database. I will attach a document that Support has issued comparing
the various types of databases and compression utilities.

Cordially,

I run a scheduled script that does something like this:
...
cd /usr/OV/databases/openview
echo "Backup of TME10 Netview databases have started..."
tar -cvf /usr/OV/backups/${WeekDay}.tar * 1>/dev/null
...
Following is a list of commands to show the environment before-and-after I
remove the backup
tar file:
absanv04:/home/root# df /usr/OV
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
/dev/lv01 3932160 1228304 69% 9092 2% /usr/OV
absanv04:/home/root# cd /usr/OV/backups
absanv04:/usr/OV/backups# l
total 2097168
drwxr-xr-x 2 root system 512 Apr 04 23:00 .
dr-xr-xr-x 40 bin bin 1024 Mar 23 07:27 ..
-rw-r--r-- 1 root system 1073741312 Apr 04 23:04 Tue.tar
absanv04:/usr/OV/backups# rm *
absanv04:/usr/OV/backups# df /usr/OV
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
/dev/lv01 3932160 3327656 16% 9091 2% /usr/OV
The backup procedure worked ok with Netview 5.1 but we migrated to 5.1.2 and
now this problem shows up. You will notice that the tar file, Tue.tar, is
abnormally large. We take daily backups of the openview directories. I
stopped it for now until I can solve this one.
Any ideas?
