BackupPC 4.0 is backward compatible with 3.x backup storage - they can be
viewed/restored etc. I just pushed an optional migration
tool, BackupPC_migrateV3toV4, that replaces the hardlinked 3.x storage in
each backup with 4.x-style attrib files and reference counting. So you can
use that to get rid of all the 3.x hardlinks if you want, but it's not
necessary.
That said, the 4.0 client configuration has changed for rsync hosts due to
the use of rsync_bpc, so a package upgrade from 3.x to 4.x will potentially
require some admin effort to update the client configs. So I agree it
won't be a completely seamless upgrade.
What do other people recommend in terms of having a new package name for
BackupPC 4.x?
