TimeDim
Copy Machine Advanced Usage
TimeDim can be used to create a time dimensional array of your files. Whenever the 'Create Backup of Preexisting Files' option is set, TimeDim will back up the old target file. The backup file is located in the same directory, under the same name with the TimeDim time suffix appended. The time suffix is: 'filename.tdm.mmhh.ddmmyy.ext' where 'filename.ext' is the name of original file, and 'mmhh.ddmmyy' is the old file's date in minute/hour day/month/year format.
For example the file 'readme.txt' date 11:55 28/aug/2007 becomes 'readme.tdm.5511.280807.txt'

File recovery. There is no facility in
the TimeDim
program that decodes the timedim backup files. When executing a
backup/restore TimeDim makes a verbatim copies of the files and
directories. (with the optional addition of the timedim file
extensions) When
restoring older versions of the file, the user has to elect which
version of the file to restore. In the example above, the user may
decide to restore the file from 28/aug/2007. It can be done by renaming
'readme.txt.tdm.5511.280807' to 'readme.txt' (naturally, clearing
or
moving out of the way the old 'readme.txt' first)

The TimeDim
dimensional array of files is a useful feature
in multi user
situations. If a file is subject to be modified by several users, and
backed up
to a central location, TimeDim keeps users from overwriting each
other's files. As it can be seen from the file name, the resolution (or
frequency) of renames can be as little as one minute. TimeDim however,
is not a substitute for a revision control system.
Clearing out old timedim files. The wildcard '*.tdm.*' is
sufficent to locate all timedim files.The following section explains it in more detail.
