Did I set this up correctly?

[customgt]

hello, i have 2 usb 500gig harddrives.
this is on sbs 2003 with exchange.

I created a device pool, with these 2 drives.
I set the file size to 450gig, with overwrite enabled and infinite append.

I leave one plugged in one week, the next week i unplug it and plug in the other one. I do full backups every night M-F

When it reaches 450gig, it will start overwriting i assume. What does it choose to overwrite, I assume the oldest files on that media label (media label being usb disk)

thanks, this is a massive program but i think i got it figured out finally

hello i dont think i did it right. If I have a 500gig USB disk, and set the file size to 450gig, when it hits 450gig it will overwrite (by deleting the entire drive!)

The file size should only be the size of the object if it is a tape that you do daily.

So if i use the 500gig disk, i should set the file size to a little over the estimated daily backup, then when it hits the 500gig limit, it will delete a media label for one day instead of a big media label for a whole week, correct?

anyone?

someone has to have advice on this...

Good Day!

I have several clients deployed with this scenario, however, I have them setup with the drives registered as removable disks. If you setup a backup to disk device and remove it, things are going to squawk. Use the wizard and setup the drives as removable.

On the file sizes, I typically set it to use 98% of the drive space, leaving the rest free for overhead.

Check your media set rules for overwrite periods and append periods. Make sure you are not locking things too long. I recommend a 12-day lock on the media sets for a two drive rotation. This keeps the data secure from overwrite but does not prevent a newer backup from running if you put the drive back into the rtation a day early for some reason (Holiday, day off, etc.).

thanks for the reply.

I also have them setup as "Removable Backup-To-Disk Device" Drives.

My Media Labels:
"Overwrite Protection Until: Overwritable"
"Appendable Until: Infinite - Allow Append"

Say I have a 400gb Removable disk drive. My backups are 100gb each. After the 4th day (Thursday), it is going to overwrite the backup (delete the whole media label and start over). It will then do the Friday backup to itself, and I will unplug it and store it and plug the other Removable disk drive in. See I just lost 4 days of backups, is thier not a way to have it delete Monday to make room for Friday???

THanks!!

is the above right?

Im thinking since i want each disk for 5 days, and its 450gig, to make the media labels 90gig.

Then set each media label to a 12day lock

thats unfortuanetly the only way i see to do this. It would have been cleaner with one media label...

I'd just stick with 1GB B2D files - BE will automatically create new ones as it needs them.
Then set an Overwrite Protection Period of however long you want to keep data for.

wouldnt having 450 B2D files make restoring alot harder?

 

[customgt]

i got it setup on 1gb labels in a 400gb folder.

when it completes a 1gb label, it stops for a minute with a yellow exclamation and beeps, then after a minute or 2 it will create the next 1gb label and proceed.

is this how its supposed to work?

and my media set says 12day overwrite, but the labels say overwriteable...??

 

[customgt]

still doing the same thing, i have not reached the 400gb limit, once i hit that ill post back on what the results are

 

[hmallett]

wouldnt having 450 B2D files make restoring alot harder?"

Not necessarily. Would having 1 450GB file make restoring any easier?

Yea I see how the restore program works now, it groups them together.
