Backup LXC and filesystem path

These scripts perform backing up a filesystem path with UID/GID saving using tar and gpg. Possible to save and upload the whole containers.

WARNING! Running this file, you accept that you know what you're doing. All actions with this script are at your own risk.

Usage

  1. Upload this folder content to your Linux system, e.g., inside of /opt/scripts folder.
  2. (Optional) Set up your rclone to mount destination drive, e.g. Google Drive, Dropbox, Amazon Drive, Amazon S3 Compliant Storage Providers (including AWS, Alibaba, Ceph, Digital Ocean, Dreamhost, IBM COS, Minio, SeaweedFS, and Tencent COS), Google Cloud Storage, Hadoop distributed file system, Mail.Ru Cloud, Mega, Microsoft Azure Blob Storage, Microsoft OneDrive, OpenStack Swift, QingCloud Object Storage, Yandex Disk, Uptobox, Zoho or another connection method(s) like ftp, ssh, sftp, http. Or mount your backup path manually, e.g. /mnt/backup.
  3. Fill your empty_password.txt with gpg key if you wish to encrypt your files or leave them empty.
  4. Edit lxc_exclude list of an excluded path.
  5. (Optional) Put your error notification commands to error_notification.sh if you would like to receive error messages.
  6. Edit your backup_container.sh with appropriate params of rclone mount (optional) and backup_path_tar_gpg.sh with appropriate backup and path params.
  7. Run:
sudo /./opt/scripts/backup_conatainer.sh -b -p /opt/scripts/empty_password.txt

with predefined destination path, or:

sudo /./opt/scripts/backup_conatainer.sh --destination /mnt/backup --password-file /opt/scripts/empty_password.txt \
  --backup --debug

Restore files:

sudo /./opt/scripts/backup_conatainer.sh --source /mnt/backup --password-file /opt/scripts/empty_password.txt --restore

Usage examples

Mount your remote drive to /mnt/backup, e.g. rclone pre-configured Google Drive mount. Add to backup_container.sh the code below before backup block:

rm -rf /mnt/backup/*
sync; echo 3 > /proc/sys/vm/drop_caches; sync
rclone mount googledrive:vps0 /mnt/backup --drive-use-trash=false --daemon --allow-non-empty; sleep 5

Optionally remove old backups, e.g., older than 60 days:

cd "$BACKUP_DESTINATION" && find . -mtime +60 -exec rm -rf {} \;

Encrypted and tar.gz packed backup of LXC-container called container_name placed in default path should look like:

# call_function "/backup/path" "$BACKUP_DESTINATION" "$ACTION" (both variables are from backup_container.sh run args)
# (archive name) (password stored in a file) (encrypt=true) (compress=true) (clean destination=false) (exclude list)
# then run task_error to pass error code and path

process_path "/var/lib/lxc/container_name" "$BACKUP_DESTINATION" "$ACTION" \
"bareos_lxc_$(date +%y%m%d).tar.gz" "$(cat empty_password)" true true false "/opt/scripts/lxc_exclude"
task_error $? '/var/lib/lxc/container_name'

# So you don't need to clean up destination path becuse your archive name contains year, month and day. Otherwise set
# them to true.

# You can also disable compression, but leave encryption enabled. In this way you'll get encrypted gpg file with .enc
# extension.

At the end of the script unmount backup path:

sync; echo 3 > /proc/sys/vm/drop_caches; sync
sleep 60
fusermount -uz /mnt/backup

Advanced usage

You can use backup_path_tar_gpg.sh directly by separate call of each backup path. Run ./backup_path_tar_gpg.sh --help for the help.
