Hello, I'm trying to do a differential backup. Each commands/scripts are launch on backup server side.
- rsync-ref: 1 script perform a complete backup to a directory "ref".
something like that:
rsync --archives \
station:/path1/ /servbasepath/ref/servpath1/
- rsync-diff: 1 script perform a differential backup to a directory "diff".
something like that:
rsync --archives \
--compare-dest=/servpath1/ \
--delete \
station:/path1/ /servbasepath/diff/servpath1/
See the following scenario:
on serv:
- rsync-ref is done
Result: large number of files are synchronized.
on station:
- the user create a new file "test"
on serv:
- rsync-diff is done
Result: the new file "test" was synchronized in diff directory.
- do rsync-ref
Result: the new file "test" was synchronized in ref directory.
- do rsync-diff
Result: nothing done, all file are synchronized.
That is my problem:
the file "test" in diff directory may/must be deleted,
because it is already on the ref directory.
I think --delete (or some other --delete-* options too) should remove
the file because it is already found in ref directory.
But Is it really a bug ?
or may I request a --delete-if-found-in-compare-dir ?
For workaround I run a script that find duplicated copies of files on
the both directories. And run the rsync-diff after.
But I work on more than 6 millions of files, the rsync and find-scrtipt took a
very lot of time.
Rsync already compare the both dir with --compare-dest then
it will probably easily append duplicated files to the delete queue.
What is your opinion ?
Best Regards
PS: Sorry for my not very well english.
