- protectomat 2.2 notes (changes for later versions are at the end):
- [This progam is available via anonymous ftp from host akutaktak.andrew.cmu.edu
- (128.2.35.1). The file is aw0g/prot26.hqx. Bugs to aw0g+@andrew.cmu.edu]
-
- Here are some programs I wrote to let you dump appleshare server
- protections to a text file and reload them. It usefull in backing
- up a server, copying parts of server volumes to new locations while
- maintaining protections etc.
-
- The sources are provided in case anyone is interested.
- Only the executables are needed to actually load or save protection.
-
- To dump protection:
- Create a file called volume_list in whataver directory the pmDump
- program is in (it can be on any disk or floppy). This file should
- have the name of each appleshare volume you want to dump. The names
- should be one per line with no extra lines or spaces. The names are
- not following by trailing colon characters. The capitilization
- is not important. Sample input:
-
- MyVolume
- BigDisk80
-
- Double click on pmDump.appl. It will read this file and process each volume.
- Protection information is dumped to a file based on the current date and time.
- The file name is protect.YYMMDD.HHMM for Year, Month, Day, Hour, Miniutes.
- A short summary is appended to the file history.YY (for current year).
-
- When pmDump finishes you need to entery OK<return> or ERROR<return> to
- acknowlege that you noticed how the run went. Usualy errors are due to
- a disruption in network service and pmDump can be rerun to get a clean dump.
- The mouse and menu's should not be used as the output file and history file
- may not be properly closed. This history file will show if this has happened
- because there won't be a 'finished normaly line' for a given run.
-
- To restore protections double click on pmLoad.appl. It prompts for a name. Type
- in the name of a dump file that pmDump made, for example:
- protect.91.0215.0910.
-
- If you only want to restore some protections or make some transformations to
- the data then edit the input file or use awk/grep to make changes to it. Say
- for example you move the folders BigDisk80:somefiles: to HugeDisk:somefiles: and
- want to copy the protection. You could keep only the lines in the protection
- file for BigDisk80:somefiles: then change the text ,BigDisk80:somefiles: to
- ,HugeDisk:somefiles: then run pmLoad. Note:There is a bug in finder haveing
- to do with copying lots and lots of files, be sure to use finder and not
- multifinder and reboot afterwards before your system crashes.
-
- Errors come in two kinds fatal and warning. Fatal errors stop before
- compleating loading/dumping all files. For example if the output file
- while dumping is on a disk that becomes full. Warning errors skip
- a given file and go on to try the rest. For example if when reloading
- a directory does not exist it is not created and the rest of the load
- is attempted. Both load and dump give a count of the number of problems
- incountered at the end of there run (if the run isn't aborted by a fatal
- error). Generaly there should be no errors.
-
- Loading writes a log of problems to protectoload.log. This will overwrite
- any previous protecoload.log.
-
- BUGS:
- The path to each file not including the volume name must be less than 256
- characters long.
-
- This version (2.2) can't read the 1.x file format.

- protectomat 2.6 changes:
- Update sources to build with THINK_C 5.0.
- Fix directory id variable to be 32bit to handle volumes with more than
- 32k directories.
-
- protectomat 2.5 changes:
- dump and restore the volumes protections too not just the directories.
- on an error don't print rubbish after the name of the bad file.
-
- protectomat 2.3 changes:
- pmDump now warns if there is a Desktop file (since Desktop manager is used by
- appleshare server no Desktop file should exit).
-
- pmDump now checks to see how many files on the disk need to be backed up how
- many kbytes of dirty files there are.
-
- pmDump now prints how old the oldest file is. If files are copied onto the server
- this date is pretty useless as it keeps the write date from the source.
