Can we run dumpall at application working time

[datactrl]

I'm used to do dumpall after work everyday. Is that possible to do it at business hours time, such as 10am, 12am, 3pm, which is within business hours and lots on line updates are still working? I just try to make a backup as uptodate as possible. If backup is made in this situation, will it has a integration problem in the backup? Thank you!

I think better for would be incremental backups (using WAL) instead of static backups?
