ReaR is not safe against blanks or special characters in file and directory names.
See https://github.com/rear/rear/issues/1372

Therefore you cannot use blanks or special characters in file and directory names
that matter for ReaR itself.

In your case mount /dev/sdb not at /run/media/vijay/disk 1 - vol
but use a mountpoint directory with a fully bash-compliant directory name,
cf. the part about "It is recommended to avoid special characters" in default.conf
https://github.com/rear/rear/blob/master/usr/share/rear/conf/default.conf#L1063

See also "Non-ASCII characters in file names" and
"Use whitespace characters in file names to fool others"
in https://en.opensuse.org/SDB:Plain_Text_versus_Locale
