interrupted Vault backup

I have a working vault (TCL2) that cannot fully be backed up due to missing file.

Missing file is "C:\Program files\M-Files\Server vaults\TCL2\FileData\0\4\59\45973-1_1.bin"
How can I resolve this or a workaround to make a successful backup?
The Vault is otherwise working but without a back up I  have no at peace
I am on version 24.2.13421.8
Please help
