gjain Posted July 10, 2003 Report Share Posted July 10, 2003 We currently have two Easy Scripts, one for daily backups and one for weekly backups. The combined amount of data that we back up from 3 servers is about 35 Gigs. We have separate back-up sets comprsing of single 50 Gigs member tape for each backup (Monday B, Teusday B etc.). Currently, we're running normal daily backups on M, T, TH, F and a normal weekly back-up on Wednesday. We re-use the daily tapes, come next week by erasing all data and doing a new backup. Currently it is taking about 10-11 hours to do daily backup, what we'd like make sure is that we're doing an incremental back-up rather than a complete back-up to reduce the amount of time used in backup since the actual data changed on the servers is less then a Gig (combined) on all servers. Could you please suggest a strategy and what would be a current sequence of actions to accomplish incremental rather than complete backup of our data. Thanks, Gaurav Jain KMC Inc.

hmseiden Posted July 11, 2003 Report Share Posted July 11, 2003 Platform independent, here's the math: MB/sec X Hours X 60 = MB to back up We expect the AIT-1 or AIT-2 to have a back up speed of 100-200MB/min. We know from you that files total 35GB and it takes 11 hours. So solving for speed we get: MB/sec= hoursx60/MB 11x60/35000= 0.018MB/min (!) My point is to tell you that you have a serious problem with your system, not to teach you algebra. Do the math to find out what it should take. I use AIT and have proper results. Your Log should also confirm these figures. I think you ought to fix the problem. Secondly, to do incremental just change the backup from Full to Normal. Good Luck!
