About delete backups on Policy of Backups

[hetfield_86]

Hello every body:

I have this situation:

I 'm going to save 10 Virtual Machines to my D2D backup system on a policy of 1 Month retention, but I have to save OSs, Filesystem to the same device and same slot used for Virtual Machines 's backups.

I know that I can define a period to overwrite the data but I don know how can I delete the old backups?

For example:

I will make 4 full backups of those backups per Month, when BE 12.5 is going to do the 5th backup, how could It delete the 1st???

Thanks for helping

Overwriting means deleting the previous backup and writing the new one.

Choose proper Overwrite Protection and Append Period values.

...and ensure that media protection is set to use overwritable media before scratch media.

[Kiran_Bandi]

Create a media set with OPP: 26 days and AP: 1 day.

Create a policy with 4 templates (1 for week), and a selection list.

Choose B2D device as destination.

Associate the Media set with each template.

Schedule the templates to run one per week. First backup job should again run on 5th week, second job on 6th week and so on...

You will get 4 different .bkf files after completing one month.

Fifth backup will overwrite the first weeks .bkf file, sixth backup will overwrite second weeks .bkf file.

Hope this is the kind of setup you want to configure...

Check the following video which shows exactly same...

And remember this is not at all possible with tape.

Thanks both for anwsering.

When you say that is not at all possible with tape, you mean that It cannot overwrite backups on Tape??

Thanks again

I'm not sure what Kiran meant by that, but it is of course possible to set up something similar using Tapes. (There will be some differences of course, since you cannot, for example, overwrite a backupset that is in the middle of a tape volume, but you can overwrite any disk BKF files)

When ADAMM (the Vertias/Symantec philpsophy of media management) was introduced, disk backups were not even supported by BackupExec

[Kiran_Bandi]

What i meant was, it is not possible to overwrite a particular backup on tape.

If OPP of a media expired, BE will use that for other backups.

Before writing into that tape, BE erases the information on that media fully.(Not the first backup set).

Hope this explains...

[Kiran_Bandi]

But to setup the same with tape, he require minimum 4 tapes.(Assume each holds a backup set).

Not possible with a single tape. Right?

[Ken_Putnam]

What i meant was, it is not possible to overwrite a particular backup on tape.

That is of course, correct.  It is not possible to delete or overwrite one backupset from a tape and leave all other data on it untouched

[Ken_Putnam]

Ok,

you of course are correct about that
