Hi My query speicific to incremental backup/recovery with btrfs send/receive option available for btrfs subvolume backups.
say i have /b1/s1 subvolume and snapshot of s1 is /b1/snap1_s1 I run btrfs send /b1/snap_s1 | btrfs receive /backup where /backup is my backup btrfs file system. Now I will take snapshot of s1 again ( after modifiying data in s1) which is /b1/snap2_s1 Using btrfs send -p snap1_s1 snap2_s2 and destination as /backup I can send incremental to backup store. My question is is there a way I can have option recover files from /backup from incremental backup or full backup (i.e. from copy of snap2_s1 or snap1_s1) And I do not want to make 2 copies of 1 full and 1 incremetal backup since if full backup is 1Gb and if there is 0.6Gb change for incremental, I would like to backup only difference for incremental backup but still would able to get option to recover files from full or incremental from backedup subvolume. is there a way I can achieve this using current btrfs send/receive and other snapshot and tracking options? thank you in advance. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
