SnapRAID TODO

This is a list of possible TODO items for SnapRAID.
This is the list of TODO items for SnapRAID.
* When fixing, before overwriting the present file, make a copy of it just in
case that the original file cannot be completely recovered.
We can always open files in read-only mode, if a write is required, we close it,
rename it to with a .bak extension, and rewrite it up to the required size.
The same for symlink if a file with the same name exist or viceversa.

It will also allow to remove disks from the array when using a dual parity

* If a file cannot be synched, for example because it was changing, or if
the file name cannot be supported, it's better to do not stop the sync process.
The sync process should stop only if the error could be caused by a disk
corruption.

* Add an option to exclude "hidden" file. In Windows files with the HIDDEN attributes,

* Implement an "undelete" command to recover missing files, without the
integrity check of the existing ones.
It should restore only missing files, without recovering modified ones
or check validity of data of existing ones.

If they do not match, stop the processing.
This can be done to avoid to use not syncronized parity and content files,
