Hi all..
I am carrying out an Eval at one of the custoemr sites...ended up =
with some problems and doubts. The netbackup documents doesn't clarify =
on these..plese send in your comments.
1. OTM=20
When backup of the whole 'C:\' drive was started with OTM =
enabled, it completed the backup partially. Exits with a status code 11. =
Suppose the total size od 'C' drive is 1.5 GB, it abcks up only abt =
450MB. The result is the same even after setting the Max cachee =
directory size to 0MB and with the 'Retry OTM' option enabled , as said =
in the veritas site. We tried out with all the guidelines for the OTM to =
work properly being given in the manual. The customer wnats to basicaly =
even backup the system files (OS fiels) and application files, using =
OTM. THere is some confusion of what OTM will enable us to backup and =
what not? Please clarify the limitations as to whether it should be used =
with only databases adn mail servers? Does it backup documents opened in =
MS Office applications? etc..
2. IDR
The same doubt with the IDR, whether after you ahve =
created the Boot diskettes for the Disaster recovery, does the data =
files being backed up also contain the OS files with the applications =
software installed on the machine? SHould we reinstall the OS and =
applications using the CD after we boot the machine using the boot =
diskettes? We didn't do the IDR exercise as he wanted us to clarify the =
OTM first. If OTM can copy the OS files, then he would allow to do the =
IDR option. The manual says=20
"A DR (Disaster Recovery) file contains specific information about =
the computer you are protecting, including:
Hard disk partition information, Network interface card =
information and NetBackup configuration information required to restore =
data files". Please clarify the same too adn if anyone has carried out =
the exercise before, send me the details of it.
3. Backup speed over network
The speed (data trasfer rate) over the 100Base-T network =
(this is a test bed, with no other machines on the switch) with the =
servers having 2 NIC cards teamed, was about 4-5MBps with file sizes of =
1-2 GB, when the file size increases or the directory size increases =
more than 4GB, the transfer rate starts with around 4MBps and drops to =
as low as 1.3MBps. This remains same whether compression si enabled or =
not. This is pretty much low when compared to the speed at which CA ARC =
Serve takes backup, even for a backup size of 7GB , the transfer rate =
was around 7-8MBps.=20
Thanks adn regards
Vasudev.
