GnuCash - log/backup file retention

[Jim Thompson]

Greetings,

Recently converted to GnuCash 2.6.3 on Mac (after 18+ years of Quicken) -
very pleased with the conversion and looking forward to being rid of
Quicken and Windoze.

Did a bit of RTFM...

- under GnuCash Preferences
- General
- Files
- Retain log/backup files
- For X days

The Help doc says:

- - - -

Note

The following options are only relevant for files saved in XML format.

Retain log files — In this section you could set your preferences about the
log files using the provided radio buttons.

- - - -

Hmmm

- have yet to figure out how to tell GnuCash to save log/backup files in
XML format

- noticed that this Help doc doesn't mention backups (only log files)

Would like automated clean-up of older logs/backups ... Do I need to set up
Jenkins or cron jobs?  Sorta remember stuff about mtime, but it's been a
couple years...

Also don't want to automatically wipe out everything after X+1 days of
inactivity, so prefer that automated clean-up be done within GnuCash...

Comments or suggestions?

Thanks,

Jim
