Backup problem cron

[msok20]

Hello,

Can anybody help me help? I want to keep copies of the past two weeks. The backup is performed once on Sundays and is to be on the disk for the last two weeks. Can't use bash to delete script. The copy is to be overwritten.

Regards

You can use two cron jobs
30 1 1-7,15-21 * 6 /backup-to-dir1
30 1 8-14, 22-28 * 6 /backup-to-dir-2

why 28 not 31? - because you can't divide 31/7. also because not every month has 31 day

for 3 weeks use shell script to rotate backups.
