Keeping an input log file that will reproduce a model, when the model has been developed over many login sessions, with backtracking caused by ANSYS crashes or database corruptions (not as common with the recent ANSYS revisions), and thousands of plots to the screen, will become nontrivial. In the event of some database corruptions, I have had to rerun a log file up to the last "good" state of the model, then work on from there. The input log can be spread out over several files with differing job names when this happens. Keeping the input file "clean" can be nontrivial with large models.
Start by asking yourself about the conditions under which your model and work could be reviewed in a "worst case" scenario. Can the stored data serve in a court case after a product failure? Are you involved with power generating equipment, aircraft, automobiles, civil structures? Can it stand up to scrutiny by people who are paid 10 times what you are?
Tape and/or CD Writers are a good means of backup. With data compression, an enormous amount can be kept on very inexpensive media, particularly with CD Writers.
In a structural model, you could inexpensively keep LOG, DB, RST, GRPH, macro, and Load Step files in many situations, with data compression and the capacity of a CDR or CDRW. If the reliability of storage media is a concern, multiple copies may be desired. Copies of the final report with image files included (not linked) should go to electronic storage media. PDF report files are nice because they are not easily edited once they are generated.
When the size of the set of files for an ANSYS job extends into the gigabytes, it may be necessary to pare down what is stored to the core required to reproduce the analysis and to permit review of the analysis results as you generated them. It is good to have the DB file(s) and associated RST file(s) for the loads of interest if possible. Postprocessing macros or instructions that were employed should be stored also.
