Relax and Recovery Issue
Hello experts,
Hope you are doing well.
Its been years since I was really happy with the Rear backup recovery.
Buy recently I have been facing a picualliar issue while creating a backup.
so here is the scenario. I accidentally installed the server into 'nvme' disk instead of 'sda'. So I was planning to take backup of the image. and recover the system under 'sda'.
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 446.6G 0 disk
├─sda1 8:1 0 1G 0 part
├─sda2 8:2 0 16G 0 part
└─sda3 8:3 0 429.6G 0 part
sdb 8:16 0 65.5T 0 disk
└─sdb1 8:17 0 65.5T 0 part /Backup <=== [should be skipped]
nvme0n1 259:0 0 372.6G 0 disk
├─nvme0n1p1 259:1 0 1G 0 part /boot
├─nvme0n1p2 259:2 0 4G 0 part [SWAP]
└─nvme0n1p3 259:3 0 367.6G 0 part
└─rhel-root 253:0 0 367.6G 0 lvm /
nvme1n1 259:4 0 372.6G 0 disk
My rear conf :
$ sudo cat /etc/rear/local.conf
OUTPUT=ISO
OUTPUT_URL=file:///Backup/rear/
BACKUP=NETFS
BACKUP_URL=iso:///Backup/rear/
EXCLUDE_MOUNTPOINTS=( '/Backup/*' )
AUTOEXCLUDE_PATH=( /Backup )
USE_RESOLV_CONF="no"
AUTOEXCLUDE_DISKS=( /dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sdb1 /dev/sdb )
EXCLUDE_COMPONENTS=( "${EXCLUDE_COMPONENTS[@]}" "fs:/sda1" "swap:/dev/sda2" "pv:/dev/sda3" "fs:/dev/sdb1" "fs:/Backup/" )
export TMPDIR="/Backup/rear-tmp/"
So , while I ran the backup it showed that was skipping the '/Backup' directory where the '/dev/sdb1' was mounted. So the total backup should be 450GB maximum. but the backup is still compressing and continue upto 3 TB. that means it is also compressing the data under /Backup directory. Because I have over 6TB of backup under that /backup directory.
output:
# rear -v mkbackup

any observation on this ?? I have tried many variations from manual but it is same.
