Configure backups

Create file inside the /lst folder called folders.lst. The script reads for directories/files to backup. Input list of all folders to backup in one row:

	/var/log/ /var/www/ /usr/files/ /tftpd/

How backup files are saved

all backups are saved by default inside your workdir/backup folder. each backup inside a seperate subdirectory.

• by default, the script saves 6 older backups. this can be changed using the BACKUP_COPIES settings (inside settings.cfg).
• first backup will be saved at /$workdir/backup/0
• at second backup, 0 folder will renamed 1 and the new backup will be saved at /$workdir/backup/0 again.
• when all 7 folders (6 older and the current - /backup/0) are full - folder /backup/6 will be deleted; 5 will be renamed to 6; 4 to 5.. etc.. 0 again will be the newest backup.

backup/0 is the newer backup. backup/6 is the oldest backup

you can set the backup destination to another folder by manually editing the backupdir setting.
