I have this situation:
|
|
|
|
* `marcos`: home server, canonical repository with all my files
|
|
(`group=backup`)
|
|
* `angela`: laptop, with a subset of the files (`group=manual`)
|
|
* `VHS`: backup external USB storage, should have a redundant copy of
|
|
all files (`group=manual`)
|
|
|
|
directly connecting the external USB drive to `marcos` is annoying, so
|
|
I usually connect it to `angela` instead, which doesn't have all the
|
|
files.
|
|
|
|
This brings up the peculiar situation that I cannot actually backup
|
|
all the files to `VHS` from `angela`, without first copying them
|
|
locally.
|
|
|
|
I have a few issues with that:
|
|
|
|
1. it fails silently: if I try to copy to `VHS` and the file is not on
|
|
`angela`, it silently fails:
|
|
|
|
[997]anarcat@angela:mp3$ git annex drop nothere
|
|
(recording state in git...)
|
|
[998]anarcat@angela:mp3$ git annex copy --to VHS nothere
|
|
[999]anarcat@angela:mp3$ git annex find --in VHS nothere
|
|
[1001]anarcat@angela:mp3$ git annex list nothere
|
|

[1002]anarcat@angela:mp3$
|
|
|
|
this shouldn't silently fail to copy: it should warn me that it
|
|
can't find a file to copy, at least.
|
|
|
|
1. it takes up more disk space: i need to download all the missing
|
|
files locally before I can transfer them to `VHS`. here's the way
|
|
I make sure files are transfered properly on `VHS`:
|
|
|
|
git annex copy --to VHS --not --in VHS
|
|
git annex get --not --in VHS
|
|
git annex copy --to VHS --not --in VHS
|
|
git annex drop --not --in 'here@{yesterday}'
|
|
|
|
the latter line is expecially problematic, because it is not
|
|
accurate...
|
|
|
|
1. it's slower: i need to write files locally before I can transfer
|
|
them. ideally, those files would be streamed, or at least I would
|
|
need to buffer locally only one file at a time and not the whole
|
|
batch.
|
|
|
|
Maybe I am missing something obvious here and there are other ways of
|
|
doing this. I am running `6.20160902+gitgbc49d8a-1~ndall+1`.
|
|
|
|
I know I could setup `angela` to be in the `transfer` group, but then
|
|
files I don't want would end up stored on `angela`: files that are
|
|
missing from other remotes, for example. Even worse, some files I *do*
|
|
want could be candidates for removal on `angela` because they have
|
|
been propagated everywhere, whereas I have a select set of files
|
|
(hence `group=manual`) that are present in `angela` that I want to
|
|
stay there.
|
|
|
|
It seems to me at least #1 above should be fixed: `copy` shouldn't
|
|
succeed when it can't comply with the requested preferred content
|
|
expression.
|
|
|
|
Somehow, I expected this to work, and maybe that's the core issue here:
|
|
|
|
git annex copy --from marcos --to VHS nothere
|
|
|
|
