Re: [Veritas-bu] poll: checkpoint restart
All of our clients are set for 30 minutes. There is very little performance impact on the backup, I don't even think you could measure it, as the checkpoint is a log entry on the client side. It's not kept on tape as someone thought. FWIW, for all of our jobs that we have to break up, we create an individual policy since you cannot restart individual streams. If a 'stream' fails, we restart just that policy. Rusty Major, MCSE, BCFP, VCS ▪ Sr. Storage Engineer ▪ SunGard Availability Services ▪ 757 N.

Re: [Veritas-bu] poll: checkpoint restart
We break ours up. If I have one very large drive that I also need to break up I will create a policy just for that server. I might have C:\ E:\ F:\ - but this is the big one so for F I do A new stream for f:\ with anything starting with a 0 -9 Then new stream And f for anything starting with a - f , new stream and g - I If for the f drive I have all numbers and letters listed I know I will get any new directories added on the backup automatically. And I have some smaller jobs. Just have to do your break up so they are good jobs (no 71's) and see how many you want to run at once. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Lightner, Jeff Sent: Wednesday, September 29, 2010 9:19 AM To: veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] poll: checkpoint restart We break our larger backups into 3-4 streams but still use checkpointing on those streams as well. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Martin, Jonathan Sent: Wednesday, September 29, 2010 10:15 AM To: Justin Piszcz; veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] poll: checkpoint restart We break our large datasets into multiple streams and restart that way.

Re: [Veritas-bu] poll: checkpoint restart
Justin, We use it and many of our backups are between 4TB and 90TB, so a restart at the 50TB point is a big plus for us. Checkpointing has been a good option for us and here, it means a lot because we are backing up right at 5PB per month.
