Daily Snapbacks

[airstand]

Hello,
I am a little confused about restoring snapbacks in reverse order.
If you want to create snapbacks every 6 hours .. you will have 4 snapback files every day....
How we have to apply them if we have 3 days with 4 files (total 12 snapback files) ?
Lets take for example one machine named VM1.
You have snapbacks like:
01022016/VM1/1.raw
01022016/VM1/2.raw
01022016/VM1/3.raw
01022016/VM1/4.raw

02022016/VM1/1.raw
02022016/VM1/2.raw
02022016/VM1/3.raw
02022016/VM1/4.raw

03022016/VM1/1.raw
03022016/VM1/2.raw
03022016/VM1/3.raw
03022016/VM1/4.raw

These are backups for example for Monday, Tuesday and Wednesday. In Thursday I want to apply the state of LVM till Wednesday (03022016/VM1/4.raw
) and I want to remove all these snapback files, after that I want to start creating the new 3 daily snapbacks.

Could you please let me know how?

Regards
