I mean a filesystem used just for a BackupPC topdir vs. a filesystem
that may contain data and/or code for multiple applications. Based
upon the nearly weekly postings on this group, it seems that many
people (myself included) initially set up their BackupPC topdir on a
filesystem containing mixed data and without the advantage of things
like LVM or ZFS since they don't realize in advance how hard it is to
copy/move/resize the topdir area due to the large number of
hard-links. It seems to me that new users should be strongly advised
to create topdir on a separate ("dedicated") filesystem on top of LVM,
ZFS, RAID, etc. to maximize flexibility. Alternatively, we can
continue to address this same issue every week ;)
