Enhancement: Rework archiver code
|
|
|
|
The core archiver code and the complementary code for the `backup` command was
|
|
rewritten completely. This resolves very annoying issues such as 549. The first
|
|
backup with this release of restic will likely result in all files being
|
|
re-read locally, so it will take a lot longer. The next backup after that will
|
|
be fast again.
|
|
|
|
Basically, with the old code, restic took the last path component of each
|
|
to-be-saved file or directory as the top-level file/directory within the
|
|
snapshot. This meant that when called as `restic backup /home/user/foo`, the
|
|
snapshot would contain the files in the directory `/home/user/foo` as `/foo`.
|
|
|
|
This is not the case any more with the new archiver code. Now, restic works
|
|
very similar to what `tar` does: When restic is called with an absolute path to
|
|
save, then it'll preserve the directory structure within the snapshot. For the
|
|
example above, the snapshot would contain the files in the directory within
|
|
`/home/user/foo` in the snapshot. For relative directories, it only preserves
|
|
the relative path components. So `restic backup user/foo` will save the files
|
|
as `/user/foo` in the snapshot.
|
|
|
|
While we were at it, the status display and notification system was completely
|
|
rewritten. By default, restic now shows which files are currently read (unless
|
|
`--quiet` is specified) in a multi-line status display.
|
|
|
|
The `backup` command also gained a new option: `--verbose`. It can be specified
|
|
once (which prints a bit more detail what restic is doing) or twice (which
|
|
prints a line for each file/directory restic encountered, together with some
|
|
statistics).
|
|
|
|
Another issue that was resolved is the new code only reads two files at most.
|
|
The old code would read way too many files in parallel, thereby slowing down
|
|
the backup process on spinning discs a lot.
