Converting incremental backups to full

I discovered that if I create a new backup for a new server, and a full backup has not been run yet, each incremental that runs until the full backup runs on schedule will run as a full. While I understand that this is the nature of incremental backups, this is highly inefficient and a waste of time and storage. I have used backup software extensively since 2004, ranging from Commvault, HP Data Protector, CA ArcServ, and Netbackup and Backup. The last time I was responsible for backups was with Commvault Simpana, and I recall if a full backup had not yet run and the incremental kicked off, then it would convert it to a full backup and mark that backup as a full.

I run BE 2012 with all latest updates. My backups run 7 nights per week; incrementals run M-Thu, Sat-Sun. Full backups run on Friday nights. My file server has about half a terabyte of data, and since I installed the software on Monday of this week (4 days ago), BE has ran incremental backups each night since, and backed up all 477GB of data each night. I have a full backup scheduled tonight, and that means its going to back it all up again, for a 5th night!

 

PLEASE, change the incremental backups, so if no full backup is detected as having ran on a backup set, then the incremental is converted to a full automatically, and marked as a full backup having been run.

...there was a post a couple of weeks ago where the user simply couldn't understand that an INCR backup couldn't run unless a FULL backup ran.

I guess if he got to see this he'd understand and would have a work-around for it!

THanks!

Yeah? Thanks for patronizing me. I've been doing enterprise backup now since 2004, I'm well aware of how an incremental backup works. Try rereading this again; the incremental backup runs, and backs up everything. The problem is, it does not mark it as a full backup, and it runs again the same way every night until the full backup runs.

...wasn't meant that way, sorry for you!

What I was TRYING to say was the an OP a couple of weeks ago didn't understand what everyone was trying to tell him...if he had the ability to implement this as YOU have proposed, he'd have his full backup with a proper INCR to follow thereafter.

By the by, I voted you up...I wasn't attacking what you have proposed, and been doing backups for a bit longer too, so I think I understand where a lot of people come from.

"Thanks!"...
