Question

linux

Are there solutions in which the server does not connect to the backup server and copies the data, but vice versa. That is, the backup server itself connects to the server and copies the information.

Answer 1

Also a good option would be bacula, where the server is the initiator of the connection.

Answer 2

Yes, for example, this is what rsnapshot does.

Answer 3

Naturally, moreover, regardless of wasps.
in fact, there are so many options that I would not even want to talk
, starting from mounting the file system on a backup server and copying them with a banal cp by cron.
wput
scp
wget
etc etc

Answer 4

rsync from the backup server can connect to the backup server if rsyncd is installed on it.

Answer 5

In fact, this is the only correct model for creating backups. The backup server must connect to the server with the data, while the server with the data should not in any way store information about where the backups are stored.
