I have 2 questions on backup options.
1.) Is anybody using probkup with the -com option.? I would like to know if this option is stable as previously i was advised to not use this option. I hope this is now stable to use.Comments Please.
2.) Redundancy check on backup -red n option. Should we be using this in this day and age as the backup layer is much more stable and robust than it was a couple of years ago. Comments Please.
-com works fine but does not provide much reduction in backup size.
-red 10 would add 10 percent to the size of your backup. it was originally implemented when UNIX tape drivers, tapes, and tape hardware were often flaky and unreliable. these days, that is not a problem. however, i have run into bad backups now and then and the redundancy might have made them readable but it was not being used.
Hi Gus. Thank you for that info. I think i would stick to the standard that i am currently using. Maybe in the future Progress could make backups with built in de-duplication and compression.
