Script ou util para remover backups antigos

Question

Estou criando uma estratégia de backup para um servidor sharepoint que estou configurando.

Tenho um backup funcionando diariamente.

A longo prazo, gostaria de manter:

• Backups diários da última semana.
• Backups semanais do último mês.
• Backups mensais do último ano.
• Backups anuais.

Se eu estivesse escrevendo no bash / cygwin, seria muito fácil escrever um script para limpar backups que não são exigidos por essa estratégia. No entanto, minhas habilidades de script no DOS são muito primitivas, então eu luto com esse tipo de coisa.

Estava imaginando se alguém mais tinha um script / util semelhante que eu pudesse usar.

Felicidades!

    

Answer 1

Acabei escrevendo um script para fazer isso. run-backup-maintenance.sh

Exemplo de uso: run-backup-maintenance.sh d7w4m12y10 / cygdrive / d / backup ". *. tar"

NOTA: Todos os backups diários devem ser gravados em: / cygdrive / d / backup / daily

Se for executado com o parâmetro d7w4m12y10, esse script garante que, com o tempo:

/cygdrive/d/backup/daily    will contain daily backups for the last 7 days
/cygdrive/d/backup/weekly   will contain weekly backups for the last 4 weeks
/cygdrive/d/backup/monthly  will contain monthly backups for the last 12 months
/cygdrive/d/backup/yearly   will contain yearly backups for the last 10 years

Aproveite!

#!/bin/bash
die () {
    echo >&2 "$@"
    exit 1
}

[ "$#" -eq 3 ] || die "Usage run-backup.sh <options> <backupDir> <artefact>."$'\n'"3 arguments required, $# provided."$'\n'"Options should be given as d#w#m#y#, where # is a number denoting how long to keep the specified backup period."$'\n'"e.g. d7w4m12y10 says that backup will keep: 7 daily backups, 4 weekly backups, 12 monthly backups and 10 yearly backups."

Existem todos os tipos de maneiras de fazer isso nativamente em cmd ou powershell, mas, como uma solução rápida, procure em EraseTemp . Use isso com o suporte a scripts e você conseguirá fazer exatamente o que está procurando.
