lvm-backup

Automation wrapper written in Bash to create backups of LVM partitions (with LVM snapshots) using Bup.

One *script* to rule them all, one *script* to find them,
One *script* to bring them all and in the darkness bind them.

Features

• Match volume groups and logical volumes to backup using regex.
• Specify directories/files to exclude from backup using regex.
• Define how much space should be retained on volume groups during snapshot creation phase.
• Set desired backup compression level (0-9) (Bup feature).
• Generate backup recovery blocks to protect against disk errors (Bup feature).
• Lower backup process priorities by wrapping them with nice and ionice.
• Print each indexed file with it's status (A, M, D, or space) (Bup feature).
• Fancy, colorized console output.

Drawbacks

• Because of LVM management, this script requires root privileges.

Dependencies

• bash
• lvm2
• git
• bup
• par2

Usage

1. Initialize Bup repository in your backup target location (specify BUP_DIR variable):

BUP_DIR=/backup/.bup bup init

2. Customize lvm-backup.cfg configuration file with your volume groups, logical volumes, backup target, etc.

• Hint: You can create as many configuration files as you want - to control which one is used, pass --config=<file> flag.

3. Backup your data:

./lvm-backup

• Hint: You can automate the backup procedure by passing --non-interactive flag (and, for example, run it periodically using systemd timers or old-fashioned cron).

4. Inspect your backup:

BUP_DIR=/backup/.bup bup ls -l --human-readable

Following command will print all your backups. You can use it pretty much the same as normal ls command to browse the data structure.

5. Restore your data:

BUP_DIR=/backup/.bup bup restore -C /tmp/test /myhost-root/latest/.

This example will restore latest backup of root partition from myhost to /tmp/test (it's a good practice to test your backups for your extra confidence).

For more restore examples see official bup-restore documentation.

ios-backup

Automation wrapper written in Bash to backup and organize media files captured by iOS devices.

Features

• Automatically mount and unmount iOS devices.
• Backup photos and videos to defined target directories.
• Rename media files to match specified date-based naming pattern.
• Fancy, colorized console output.

Drawbacks

• There is no support for incremental backups - duplicates are not recognized during backup stage.

Dependencies

• bash
• gvfs-afc
• rsync
• exiv2
• mediainfo

Usage

1. Customize ios-backup.cfg configuration file according to your preferences.

• Hint: You can create as many configuration files as you want - to control which one is used, pass --config=<file> flag.

2. Backup your iOS device:

./ios-backup

• Hint: You can automate the backup procedure by passing --non-interactive flag.
