Implemented delete-all-but-n and delete-older-than.
Implemented compacting.
Added the --dry-run option, which currently works for deleting and compacting, but not restore or backup.
Added output to console for use with dry-run, and added option to redirect this to the log for use in service mode.
Still needs a work over in terms of error handling, progress reporting, warning output, refactoring etc.
Also misses the volume reuse/reclaim algorithms.
But it passes the unit tests now, with and without a local database.

There is now an option called "vss-use-mapping" that activates DefineDosDevice and uses short DOS like paths.
I also find a little place that could be a performance problem, so maybe this fixes the issue even without the mapping.

This fixes issues #144, #577 and #320.
This update introduces a new options called "symlink-policy" that can be set to "store", "ignore" or "follow".
The default setting "store" means all symlinks are recorded as symlinks and recreated as symlinks on restore. This is chosen as default because it is the best replication of the actual disk contents.
Setting it to "ignore" simply means that no information is recorded about any symlinks.
And lastly, setting it to "follow" reverts to the previous default of treating symlinks as if they are normal files/folders.
Caveat: On Windows, you need Administrator privileges to create symlinks (when restoring), but not for reading them (on backup).
Since this change meant that the file attributes must be read, I also added support for the option "exclude-files-attributes", that can be used to ignore/exclude files with certain attributes, such as "hidden", "archive" or "encrypted".
Since I had to much about so much with getting the symlinks supported on Windows, I also added some extra logic to the Windows file handler, so it can now handle files and folders with up to 32k chars in the path. The logic is done so that the normal System.IO operations are used for paths with less than 260 characters (MAX_PATH), and on error or longer paths, the Win32 Unicode API is invoked. This should give maximal backwards compatibility and still allow backup and restore of files with long paths.
This commit also includes a BlockingQueue implementation that is supposed to make file/folder enumeration faster, but this has not been implemented because Duplicati depends on having a "whole world" view of the files and folders before running the backup (i.e. deeper changes required for this).

Status: Fixed
Duplicati now defaults to not upload a backup if nothing has changed.
This is indicated by a light-green check mark in the status window.
The option --upload-unchanged-backups can be set to revert to the previous way of working.

Changed to the AWSSDK library, which fixes a few quirks, but basically seems to be the Affirma version slightly renamed.

This commit includes an option to create an unencrypted verification file.
There is now a check to see if all volumes mentioned in the manifest exists,
before performing backup/restore operations.
This check is also performed on cleanup.
There is now a check that prevents auto-cleanup from removing more than
2 orphan files.
If a delete-older-than or delete-all-but-n-full is interrupted, the leftover
files will not be auto-deleted but must be deleted with the cleanup command,
which allows the user to see what files are delete.
Update issue #360
Status: Fixed
There is now a complete verification chain, where the manifest hashes are verified backwards.

Now allows 1% (max 1 hour) slack in the time difference.
Can be disabled with the --disable-time-tolerance flag.

Status: Fixed
The implementation is a mix of the the three mentioned methods (issue #247).
There is a commandline option called --open-file-policy, which can be set to
"ignore", "snapshot" or "copy".
The "ignore" setting does the same as previous version, simply exclude the file from the
backup set.
If the setting is either "snapshot" or "copy", and the file it locked, it is opened in non-excusive read mode.
Once open, a in-memory signature file is generated. This is compared to the previous signature to detect changes,
just as the normal operation. If the file has not changed, the file is skipped as it would normally be.
If the file has changed and the policy is "snapshot", the file will be processed as normal,
but during the file read, a new signature is generated. This new signature is stored
in the signature archives. When writing the new signature, it is compared to the original signature.
If the file has changed during the backup operation, a warning is written to the output log.
If the policy was set to "copy", the modified file is copied to a temporary location,
while a new signature is generated. If the copy fails due to a file change, the file
is omitted from the backup set. If the copy succeeds, the file is known to not have changed
during the first access and the copy, which gives some assurance that the file is not
actively being written, at the expense of a copy operation.
The default setting is "snapshot", because this is likely to work in most scenarios,
and potentially produces a broken file rather than guarantee a missing file (by "ignore").
Note that when reading an open file, there is always a chance that the file is being written,
so you may end up with a broken file in the backup. This is also true for the VSS and LVM snapshots,
except for VSS-aware applications.
The "copy" method is meant to minimize this risk, but there is no guarantee that the file is in an
acceptable state, just because it has not been written for any period.

Status: Fixed
USN is now activated by default on windows, but requires Administrative privileges.
If it fails to activate, it is silently ignored, and normal filesystem enumeration is used.
Set --usn-policy to:
"on" to get a warning if it fails,
"required" to abort the backup if it fails
"off" to disable USN
"auto" to silently ignore a fail

Added the --vss-exclude-writers option.
Update issue #260
Status: Fixed
I have now added a --vss-exclude-writers commandline option.
I had another look at the other supported options, and I consider this the most important.
I made the simplest possible version, so it only supports class guids, not component names
or writer instance ids.
If you need any of the other switches or the component names, please let me know.
I would also be interested in hearing that it actually works (I get no errors, but thats no proof).
You can specify multiple writers with a semicolon: --vss-exclude-writers="{d61d61c8-d73a-4eee-8cdd-f6f9786b7124};{0bada1de-01a9-4625-8278-69e735f39dd2}"
If you need the guids, you can get them with the following command in a command prompt:
vssadmin list writers
