+What is the difference between a repo on an external hard drive vs. repo on a server?
|
|
|
+-------------------------------------------------------------------------------------
|
|
|

|
|
|
+If Borg is running in client/server mode, the client uses SSH as a transport to
|
|
|
+talk to the remote agent, which is another Borg process (Borg is installed on
|
|
|
+the server, too). The Borg server is doing storage-related low-level repo
|
|
|
+operations (get, put, commit, check, compact), while the Borg client does the
|
|
|
+high-level stuff: deduplication, encryption, compression, dealing with
|
|
|
+archives, backups, restores, etc., which reduces the amount of data that goes
|
|
|
+over the network.
|
|
|
+
|
|
|
+When Borg is writing to a repo on a locally mounted remote file system, e.g.
|
|
|
+SSHFS, the Borg client only can do file system operations and has no agent
|
|
|
+running on the remote side, so *every* operation needs to go over the network,
|
|
|
+which is slower.

Can I backup from multiple servers into a single repository?
