Changes with server 2.4.0 beta

• Allow setting group id while adding new clients

Major changes with client 2.4.x beta

• HTTPS proxy support (only with SChannel on Windows for now)
• Parallel hashing improvements

Changes with client 2.4.1 beta

• Fix FreeBSD compile issue

Changes with client 2.4.0 beta

• Reset reconnect tries if more than 30min between reconnects
• Only set reconnect_tries to 50 if it wasn’t set higher previously
• Tool to read volume and write zeros to blocks which cannot be read
• Set socket window size to 3MiB send buffer and 128KiB recv buffer for client on Windows
• Fix incr image bit clashing with full file backup bit
• Remove result writing via pipe fixing some async indexing hang-ups
• Fix search for snapshot if VSS path is the root of a volume
• Fix parallel hashing with VSS components
• Hard code not following default wine z: symlink to root of fs on non-Windows
• Functionality to interrupt parallel hash loading threads on clients
• Don’t parallel hash files smaller than 2048 bytes
• Add to db if there is a sub-directory because that one can be deleted and should then be removed from the db (Linux/MacOS)
• Do not quit indexing with “no backup dirs” if components are selected for backup

Changes with Restore CD 2.2.2 beta

• Fix GPT restore with restore disk being (slightly) smaller

Upgrade process

As always: Replace the executables (via the installers) and the database of the server/client will be updated on first running it.

Place the files from the update directory into C:\Program Files\UrBackupServer\urbackup or /var/urbackup to auto-update clients. Disable Download client from update server in the server settings to prevent the server from downloading the current version.

On Linux e.g. with this update script: https://github.com/ptempier/get_urbackupclient/blob/master/updateclient.sh

Downgrade process (server)

Stop the UrBackup server, restore C:\Program Files\UrBackupServer\urbackup or /var/urbackup from a backup before upgrade and then install the previous version over the beta release.
