Hi There,
Good News/Bad News? Legato will "always" reference the last FULL backup or
lower level differential or the last backup (incr). Meaning to do a restore
it will build a picture of a full "image" on a certain date and use any
number of incr's and diff's plus your last full to get a complete picture as
of that certain date.
>From a backup perspective: Meaning, unless you do differentials only (level
1 - 9) and occasional Full's you will struggle to get it to reference
certain backups on certain days.
So, if you do incremental's it will reference tha last backup and backup
anything that has changed.
With Differentials it will reference the last FULL or the last lower level
differential. You can play with differential levels and end up with a type
of "smart" incremental (meaning your restore takes up less tapes). (I
suggest taking pen and paper and writing the numbers 1-9 down randomly (on a
week schedule), and seeing which day will reference wich other day's backup
- to get a clearer picture - it worked for me).
But as far as I am aware, if there is a full backup in-between your incr's
and diff's will reference that. I might be wrong (it has occasionally
happened before ...)
:p
I hope this makes sense, and that it helps,
Regards,
Riaan

Subject: [Networker] Legato Backup Level
Hi guys,
I wanted to know if someone knew where I can find some real indepth info
on legato and backup levels. I want to understand how the backup levels are
affected when we need to restores. I want to look at setting up a system
where the full backup of 1 day is skipped and the next days backup goes to
a previous backup.
Example:
I backup a full on monday, and then I backup full on friday. then when i
do a level 7 backup on sunday i want it to reference the backup on monday
and not the friday backup and backup data such that it backups the client
as if no full occured on friday.
this one has been getting me for sometime... hey anything to help the brain
feel like its straining.
