Re: [WriteLog] Back-up??

["A. Sewell" <n5na@att.net>]

Writelog DOES write a journal file.  From the Writelog help file:

File Backup
The entire QSO data base is stored in memory, but is written to disk, or 
read from disk using the File Save and File Open operations. As with 
important data on any computer, the QSO data base should be periodically 
written to magnetic storage to protect against loss of data in a power 
failure.

WriteLog automatically protects newly entered, but not yet saved data. A 
separate journal file of just the QSO data is kept between Save 
operations. This journal file (with extension _jou.adi) is used in the 
case of a failure when there are QSOs that had been added to the log 
(and therefore to the journal file as well), but no Save operation had 
been used on the full data base. The recovery is automatic: just do a 
File Open of the WriteLog file you last saved and WriteLog will offer to 
recover the QSOs in the journal file.

Whether you chose to recover the journal or not, WriteLog renames the 
journal to <filename>_bck.adi (where <filename> is the name you have 
chosen for the file.)

WriteLog deletes the journal file at the end of a successful Save 
operation, so the journal file contains only those QSOs that do not 
appear in the newest WriteLog file.
