Mint Backup for DeDuplication

Postby grimdestripador on Wed Jan 04, 2012 5:24 pm

Does MintBackup use deduplication?
where deduplication is the ability to compare duplicates and remove the duplicate (exact/unchanged) files.

Perhaps the tool/utility can be programmed to allow differential backups. In a nutshell one would checksum all new files and compare with the old files (after comparing permissions). Once you find one, delete the duplicated file then sym-link the new partial backup with the full backup.

on BSD unix:
ms snapshot oldsnapshot
mkdir snapshot
cd snapshot
find -d ../oldsnapshot | cpio -dpl -
rsync -aE source/ ./

where ../oldsnapshot is the old backup of your data
snapshot is the new backup
source is the thing you want to backup.
