I’m running urbackup client (Debian) and server(Ubuntu) in local network. Server detects client and starting full file backup of /var, /etc and /home directories setted as default. After few seconds of backup process start client machine freezes up, server showing “indexing” and nothing changes for hours. Even after forced stopping of backup process on server, client doesn’t recover or responding. A dattobd kernel module is installed on client. After beginning of backup in client’s root directory appears datto snapshot (so i suppose datto is working). Also was a try on Debian client installed on virtual machine using EXT4 filesystem with same behavior.

Seems the client was restarted after 10min… Maybe it hangs when creating snapshots. Looking at if the snapshot script is running should give an answer. Maybe you stoped it? Can’t tell more from the log.
So, if machine was freezed, how can I watch snapshot script is running? Btw, server logs that he can’t get file list from client.
UPD. The last command urbackupclientbackend process executes before client’s machine freezes up is in datto_remove_filesystem_snapshot script.
