The wonderful dar Disk Archiver is used for
the heavy lifting, together with the The Parchive suite in these scripts.

'dar-backup' lives at Github
I have cloud storage mounted on a directory within my home dir. The filesystem is FUSE based, which gives it a few special features:
- a non-privileged user (me :-)) can perform a mount
- a privileged user cannot look into the filesystem --> a backup script running as root is not suitable
I needed the following:
- General purpose backup system, which has saved my bacon on some occasions.
- Backup my cloud storage to something local (cloud is convenient, but I want control over my backups).
- Backup primarily photos, video and different types of documents.
- Have a simple way of restoring, possibly years into the future.
- 'dar' fits that scenario with a single statically linked binary (kept with the archives).
- There is no need install/configure anything - restoring is simple and works well.
- During backup archives must be tested and a restore test (however small) performed.
- Utilize Parchive to create redundancy to increase the chance of fixing bitrot in the archives down the line.
- Verify archive's integrity, after it has been moved around, or copied somewhere.
I do not need the encryption features of dar, as all storage is already encrypted.
