I am using: tarsnap 1.0.41
Once tarsnap sees a non-flag on the command line, everything else is treated
as a non-flag. So that's why this wasn't a dry run.
Got it. So basically whatever tarsnap examples are there in the docs if
there’s a flag in the example all the flags in the command should start
right there and exhaust one by one (if I am passing more than that’s given
in that example) and then rest of the args/fields of the commands should
be passed after that.
That makes sense, data was copied into a new archive so it's no longer unique
to that archive.
- new-prefix_test: its list of files is much smaller than the source archive.
But when I compared the file list they match exactly until new-prefix_test file ended.
As you see there is no ".part" in its name.
new-prefix_test 36 MB 15 MB
(unique data) 205 kB 37 kB
That's very strange. Is there anything interesting about the next file in the
old archive after the new archive stopped? I'm wondering if somehow tarsnap
failed in the middle of copying the archive... if that happened you should
have seen an error message though.
Internet disconnection definitely had happened. Also, the next file was
Also: tarsnap-gui appends "Job_" as "Job_{job name}_{timestamp}" to every
archive name. Can I choose not to add that "Job_" or decide on my own how to
name the archive while still using the GUI?
I think the GUI lets you enter your own archive names when creating a single
archive, yes
I meant to ask if I want to schedule/automate the backup via GUI then I
assume GUI just take the job name I have given and prefixes “Job_” to it
and adds a timestamp suffix and creates the archive. I meant can I choose
not to add that “Job_” to it? Might be a good GUI option really.
I will try the commands again and see how it goes. Thanks.
