Sure, but if there is a canonical location where all programs put their
backups this is the preferred one and sysadmins knows where to look...
Please note that while I agree that such a location has not been agreed
upon, /var/backups is the de facto standard and it is even mentioned as
reserved in the FHS
The following directories, or symbolic links to directories, are
required in /var.
Several directories are `reserved' in the sense that they must not be
used arbitrarily by some new application, since they would conflict
with historical and/or local practice. They are:
On my Debian sid, /var/backups contains atp, dpkg and others' backups
(group, gshadow, passwd, shadow). This is similar to some lenny systems
I (still) have.
