Linux Server backup with overwrite

Dan Colbert Jun 7, 2018 8:55 AM

I need to set up a nightly backup for our Linux server.

The first backup works just peachy, but when I run it a second time I get this:

While I get no actual raspberry (or other unsavory actions) from the system, I do get a "Cannot overwrite the existing file" error. Has anyone overcome this? I can probably build a shell script to remove the file beforehand, but would prefer that the tsm command take care of that.

Is there an undocumented switch for the backup to overwrite?

Thanks in advance,

Dan

Hi Dan,

Are you specifically trying to overwrite the backup ? If yes I would recommend against that as you never now what might happen.

I would suggest using the -d parameter to append the date to the filename, that would solve your issue.

tsm maintenance

However if you want to overwrite, have you tried running the command in sudo ?

Thanks Ciaran, I do want to overwrite the backup in one command. It is not our regular backup, but an additional one we're doing for another purpose.

I know I can manually remove and recreate the file, but I'd like to do it in one step, rather than work around a what I think is a limitation of tsm. Using "sudo" doesn't work, nor should it really, because the backup is part of "tsm maintenance" - Tableau owns tsm so sudo is unnecessary.

Thanks,
Dan

Hi Dan,

It does seem indeed that there is no overwrite option in the command for the moment. You are right, a script will be the only option.

You can voice your idea to get an additional option added to the command by posting in our ideas section.

I thought that might be the case - thanks for the reply.
