Remove after the following number of days—If you are moving deleted files, you can specify
a length of time, in days, to maintain the moved files. A moved file that is older than the specified
number of days will be deleted. Storage Mirroring checks for moved files that should be deleted
once daily at 8pm. Only the date, not the time, of the file is considered when moved files are
deleted. For example, if you specify to delete moved files after 30 days, any file that is 31 days
old will be deleted. Because the criteria is based on days and not time, a file that will be deleted
could have been moved anytime between 12:01am and 11:59pm 31 days ago.
NOTE: If deleted files are moved for long enough, the potential exists for the target to run
out of space. In that case, you can manually delete files from the target move location
to free space.
If you have Ignore Delete Operations enabled on the source, the Move deleted
files setting will never be invoked because there will be no delete operations
performed on the target.
Do not include the Recycler directory in your replication set if you are moving deleted
files. If the Recycler directory is included, Storage Mirroring will see an incoming file
deletion as a move operation to the Recycle Bin and the file will not be moved as
indicated in the Move deleted files setting.
Alternate data streams that are deleted on the source will not be moved on the target.
Encrypted files that are deleted on the source will only be moved on the target if the
move location is on the same volume as the replication set target path.
Compressed and sparse files that are deleted on the source will be moved on the
target, although the compression and sparse flags will only be retained on the target
if the move location is on the same volume as the replication set target path.
