It is possible. You could either instruct BackupPC to do full backups
only (set $Conf{FullPeriod} = 0.97 and $Conf{FullKeepCnt} = 3660). Or
configure Full and Incr backups accordingly:
(10 years, every 7 days)
$Conf{FullKeepCnt} = 523;
$Conf{IncrKeepCnt} = 3137;

How many clients are you talking about and how much data is on them?
You're talking about a pretty HUGE amount of data. I'm wondering which
machine, disk subsystem and file system will be able to handle that. You
might be talking about billions (10^9) of files here.

And don't forget a second layer of backup: What if your backup server
crashes hardly or burns down? What if some subtle file system bug is
triggered and eats all your data? Every file which is stored in only one
location has to be considered lost.

HTH,

Tino.
