A tarball based incremental backup tool written in B shell script.
- Tarball based
- Easy to backup
- Easy to extract all/specific files
- Portable: written in B shell script
- Default to xz compress
- Lightweight and ready to use
In summary, use sheltar when you want to
- back up files to be extracted other platform
- migrate data across boxes
- synchronize files across boxes continuously .
You may wonder "My OS(platform) has awsome backup tools. Why need another?" Yes. I know and I'm using them too. However they tend to have their original format which is not portable to another tools and they themselves aren't portable. Then is your backup available when you lost your machine? Are you able to recover files from a machine other than original machine? If you're afraid not, use Sheltar
Another situation is when you migrate (or synchronize) data across boxes.
I admit rsync is one option to do it and you may want to use it. Suppose your network is
unstable or slow. You'll catch up with migrating data via USB memory. Then, how?
Tarball is a platform dependent format
but the options of tar commands differ from platform to platform. Then use sheltar
or bother to consult man many times.
Prepare backup list and backup dir
$ ls *.sh > backup_list.txt
$ mkdir backup_dirDo it
$ path/to/sheltar backup backup_dir backup_list.txtThat's all
The same as backing up
$ path/to/sheltar backup backup_dir backup_list.txt$ path/to/sheltar extract backup_dir$ path/to/sheltar extract backup_dir file1 file2 ...BSD.
