Hi,
It would be extremely helpful if the expert minds in this forum could help me
with below concerns related to backing up data using Symantec NetBackup.
Background
Our system has a folder containing millions of small files spread across 1000s
of sub folders running into more than 500GB that needs to be backed up on a
daily basis. The backup usually starts end of day and is ideally supposed to
finish before users start accessing the system the following day. However, the
current backup using Symantec Netbackup takes lot of time and hence, this
impacts the system performance. I assume this is because of the current backup
approach used by Symantec is based on file-level backup.
The current backup policy has a monthly full backup, weekly differential backup
and daily incremental backup. However, the daily backup itself takes more than
double the desired time. Symantec client version is 7.6.02.The server is a
physical server having Windows Server 2003. The drive is dedicated to storing
the files.
I am looking for a solution that would provide the fastest backup in order to
ensure that backups are completed before users start accessing the system in
the morning.
1. What is the best approach for backing up millions of small files spread
across 1000s of folders using Symantec Netbackup?
2. I understand that flash backup feature in Symantec uses block-level backup
and this would be ideal approach since there are lot of files involved?
3. What are the disadvantages of using Symantec Flashbackup feature?
4. Does installing Symantec SAN client without having fiber channel offer any
improvement in backup speed? I read on some forums that you should use SAN
client only if there is fiber channel support.
5. Would moving applications to Virtual Machines hosted on Vmware environment
provide any improvement.
PS: Backups are not my domain of expertise and hence, I would like to apologize
in advance if I have mentioned something absurd. Secondly, changing the
application file structure is not an option :(
Cheers,
Shaheen
