Package: rsnapshot
Version: 1.2.0-1
Severity: wishlist
It would be most helpful for rsnapshot ro support remote snapshot_roots.
I know that the online FAQ says:
"Q: Can I set the snapshot_root to a remote SSH path? I want to push my
backups to a remote server, rather than pull them from a remote server.
A: Currently this is not possible. This would be a nice feature, but
several questions remain unanswered:
* How can the integrity of the snapshot root be guaranteed if one or
more remote servers have write access to it?
* When snapshots are rotated, which of the potentially several
remote servers connecting is responsible for performing this task?
* One possibility is to have a "staging" area for files to
be transferred to, then have rsnapshot sync from this
staging area into the snapshot root. Can this be
accomplished without taking up double the disk space? "
This seems to suggest that the primary difficulties with remote
snapshot_roots involve the potential for multiple remote servers to push
into the same snapshot_root.
There is, however, a very simple way to accomplish this:
Document that there can be at most a single server using any given
snapshot_root. If multiple servers are pushing backups to a single
backup server, each needs its own root. I can see no reason why not to
support this functionality, at the very least.
Another option would be to add one additional level of indirection by
automatically creating a directory inside of snapshot_root containing
the name of the connecting server, and to include the daily.* &cetera
directories for each server in a directory unique to that server. This
is really just a way to automatically implement the above solution.
