We break our larger backups into 3-4 streams but still use checkpointing on those streams as well.

It's much easier for me to say to an app group "all of the backups finished except /lun7 and I'm rerunning that now" than "The backup is 80% complete and we're rerunning it from wherever it failed." For backups that run 48 hours, we just feel more comfortable knowing exactly what backups are complete and which directories can be restored from now, rather than hoping the whole thing completes later. -Jonathan -----Original Message----- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Justin Piszcz Sent: Wednesday, September 29, 2010 10:10 AM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] poll: checkpoint restart Hi, I was curious, as backups get larger and larger, how many out there are using checkpoint restart (yes I know it slows down the backups a bit) but it saves a lot of time having to start a 2-8TB backup again from scratch if something goes wrong (network issue or otherwise). Is it becoming more commonplace to use this?
