backup.pl options -r

[aph]

The ./backup.pl --help command returns

Code: Select all

usage: backup.pl -d /data_backup/ [-c bzip2|gzip] [-r 30] [-t nofullbackup]

What does -r stand for? What is the significance of the number behind the -r option?

[reneeb]

-r 30 means "keep the backups of the last 30 days".

[andy17d]

Does this mean that after using the -r option 30 backups older than 30 days will be automatically deleted?

[jojo]

yes
