pdumpfs May be a Casualty of Upgrade to Wheezy.
The daily system backups had failed for several days so it was
time to investigate and I found that the time of death was after
upgrading squeeze to wheezy.
Pdumpfs is useful because each day's new backup consists
of hard links to all previous files plus any new files that have
been written since the previous backup.
After the upgrade, pdumpfs exits with errors related to
ruby libraries and it's game over.
To recover files, one mounts the backup medium, cd's to
the year/month/day/home/user/files and simply copies them
wherever they need to be. It's simple and most important, one can
stick a suitably-scized thumb drive in to a usb port and forget
about it until it is needed.
Such programs as dump, restore and rsync are fine but need more
media and attention for use as backups.
The description of pdumpfs describes it's backup strategy
as similar to something called plan9.
All constructive suggestions are greatly appreciated.
