Question Cron job every Friday except 4th

Hi,

I'm looking for a way to run a backup in the cron every Friday, except every 4th Friday (as we do monthly backups then).

The monthly backups are not the 4th Friday of each month, but every 4th Friday (i.e. we don't want this backup to run on x Friday, then the Friday 4weeks/28days later).

This backup also runs Monday-Thursday getting called normally from the cron, but currently it is run manually on Fridays due to this. I understand we will need another script with validation, and call the normal backup script, then put that in the cron - but unsure how to do it.

Thanks in advance!
Rab

svn-fast-backup(1)					      General Commands Manual						svn-fast-backup(1)

NAME
svn-fast-backup - very fast backup for Subversion fsfs repositories. SYNOPSIS
svn-fast-backup [-q] [-k{N|all}] [-f] [-t] [-s] repos_path backup_dir DESCRIPTION
svn-fast-backup uses rsync snapshots for very fast backup of a Subversion fsfs repository at repos_path to backup_dir/repos-rev, the latest revision number in the repository. Multiple fsfs backups share data via hardlinks, so old backups are almost free, since a newer revision of a repository is almost a complete superset of an older revision. This is good for replacing incremental log-dump+restore-style backups because it is just as space-conserving and even faster; there is no inter-backup state (old backups are essentially caches); each backup directory is self-contained. It has the same command-line interface as svn-hot-backup(1) (if you use --force), but only works for fsfs repositories. svn-fast-backup keeps 64 backups by default and deletes backups older than these; this can be adjusted with the -k option. OPTIONS
-h, --help Shows some brief help text. -q, --quiet Quieter-than-usual operation. -k, --keep=N Keep a specified number of backups; the default is to keep 64. -k, --keep=all Do not delete any old backups at all. -f, --force Make a new backup even if one with the current revision exists. -t, --trace Show actions. -s, --simulate Don't perform actions.
