Souborový systém Btrfs: jak pohodlně a efektivně zálohovat - 11. Únor 2020 - 0:00
[6 minut čtení] Nedílnou součástí správy diskového systému je také dobré zálohování. V minulosti se používaly utility jako tar, rsync nebo pokročilejší nástroje jako Bacula. Pokud ale používáte Btrfs, můžete zálohovat lépe. Dříve se zálohovalo nástrojem tar, pak přibyly různé další nástroje. Výborný je např Rsync, jeho nadstavba rdiff-backup nebo se používají nástroje typu klient-server, například Bacula. Nyní se souborovým systémem Btrfs můžete zálohovat jednodušeji a navíc i efektivněji.
