Pretty new to CRON but have been messing with Ubuntu for a while now
Here is the situation/problem I have run into you.
I currently run a very basic back procedure by executing a daily CRON job which copies all data from one directory to a USB drive & date stamps the copy:-
Which has been working prefectly well, however when I checked it last I realised the USB drive had filled up & there was no space to continue the backup.
Is there an easy way to check the date & overwrite the oldest copy, therfore never filling the drive up so the backup will always be successful.

sa2(8) BSD System Manager's Manual sa2(8)NAME
sa2 -- Generate a system activity daily report file.
SYNOPSIS
/usr/lib/sa/sa2 [-dgpu] [-n mode] [-e time] [-f filename] [-i seconds] [-s time]
DESCRIPTION
The sa2 command is a shell script used to invoke the system activity reporter sar for purposes of generating the standard default daily
report file. The report file generated is, /var/log/sa/sardd where the dd represents the current day of the month. The sa2 options are the
same as those documented in sar(1).
When sa2 runs, it will also remove data and report files, found in /var/log/sa, that are more than one week old.
The sa2 command is intended to be started by cron.
EXAMPLE CRON ENTRY

# every 20 minutes for 12 hours
# 20 minutes = 1200 seconds
# 12 hours with 3 samples each hour = 36 loops
0 8 * * 1-5 /usr/lib/sa/sa1 1200 36
# After the 12 hour period,
# collect a system activity report
30 20 * * 1-5 /usr/lib/sa/sa2 -A
FILES
/var/log/sa/sardd Default daily report file.
/var/log/sa/sadd Default daily data file.
