QB backup

In using QuarterBack I am a little confused about setting the archive bits on a backup. If I make a backup once a month of my hard disk partitions and set the archive bit on it, will QB, the next time I do a backup, automatically backup only those files that have changed? If so, how does it write to the proper floppy in the backup set? What's the difference between this and an incremental backup? Why would I, as the manual states, need to keep an incremental set of floppies and a full backup set of floppies? That's a lot of floppies. I would just like to make a backup of my partitions once a month and only add the files that have changed to save time. No need to backup every file is there? RJ……….on AutoPilot

RJ, I have QB 5.03. Archive bits work as you have described. I don't think QB will write into the middle of an existing archive. In essence, the incremental backups are new archives. If you are concerned with minimizing the number of floppies used, they describe a procedure in the manual whereby you always have only two archives: the master and the incremental. After a point, if you can afford it, backup to tape is the only way to go! QB has improved its support of tape backups recently. Gary from rainy Fort Wayne, IN – via Whap!

I don't understand what incremental backups are. Are they floppies containing backup files of only those whose archive bit changed? If my partition gets corrupted and I want to restore it, what good is an incremental backup if it doesn't have all the files on it? It seems to me, only a full backup can restore my partition. I would like to see a backup that you can write to that just adds the changed files to the backup. That way, it would just ask for the proper disk to be inserted that has the file in question. As it now stands, I must use 22 disks to backup one partition just so I can add those few files that have been changed. RJ……….on AutoPilot

Here is the way I do it. Backup everything to disks labeled FULL BACKUP and set the archive bits on Sunday. Every day after that for the next week do an incremental backup to disks labeled INCREMENTAL BACKUP without setting the archive bits. Depending on how much work you do this might only be a few disks worth of information. This will backup everything that has been changed or added since your last FULL BACKUP. You just keep writing over the INCREMENTAL BACKUP disks every day. If you need to restore something just stick in your INCREMENTAL BACKUP disks and choose it from there. That is the lates version. If it is not on the INCREMENTAL BACKUP disks then stick in your FULL BACKUP disks and choose it from there instead. If your partition gets corrupted, restore your FULL BACKUP disks. Then restore your INCREMENTAL BACKUP disks. Then you will have everything. This is all explained better in the manual but I thought I'd give it a go anyway.

Thanks, it seems a little clearer now. RJ……….on AutoPilot
