Presently we are taking backup of a filesytem by copying it to remote backup server and from there it is written to tape drives. few months ago it used to take 30 mins for 5 Gb, but now its taking 5 hrs for 5 Gb. what could be the possible bottle necks and what are the areas we should concentrate, so that we can resolve this problem. Please provide your valuable inputs.[o:p][/o:p]

Thanks. We'll let you know when a new response is added.

you could have large downloads going on (i.e. software updates or other backups accross the network) which would cause performance issues.

Or it could be something as simple as AV getting in the way where it didn’t before. You would have to look at what has changed in your environment in the last few months.

Alternatively can your switch/hub/network appliances handle jumbo packets? If they don’t this will seriously hinder performance.

    First review your network segment, all interfaces including local and remote server, switches, routers and so, needs to be reviewed in order to ensure they are using all available bandwith. Then check I/O performance in both servers, local and remote. It is the tape drive involved in the transfer process? I mean, do you transfer the entire backup over the network directly to your tape drive? If so, consider first to save the backup to hard disk and later save it to your tape device. And last, review the processor performance in both servers to determine if there is another processes that is slowing down server's performance. Regards.

    I've had an issue where the data was a certain size but over time the log file that accompanied the data was massive and growing. If it has gradually gotten slower over time ensure the log file size hasn't gotten out of control.
