You’ll have to take a look at running applications on the client that may change the backed up files during the backup. If there aren’t any or you start/stop them in the pre/post file backup scripts you’re ok. Otherwise the backup might not be consistent.

Ok, but is there any issue if we don’t take backup of the snapshot?
Will there be any problem or issue during restoration?

If you don’t use a snapshot, the files that have changed during the backup will be inconsistent. Whether or not that is a problem depends on your application.

E.g. If you’re backing up databases and your index files don’t match data files or you are referencing between multiple databases, the restore will succeed but your database will be inconsistent and potentially useless.

If you’re just backing up log files, some log files being older than the other is only a problem for legal investigations.

I can take the backup of my Linux machine (centos 6) which uses ZFS filesystem but the problem is I can’t restore the backed up file.
Also, I disabled the firewall, but still showing timeout error.
Please let me know what the issue is and also note that my client machine doesn’t have a “urbackupclientgui” as I installed via CLI.

I m also having the same issue, my urbackup server is centos 7 and client is fedora 25 (" NO urbackupclientgui " installed).
Backup is working fine but i not able to restore, showing timeout error.
please help me to find out a solution for this.
