I have no idea how the "Current Implementation Restrictions" (listed in <http://www.bacula.org/dev-manual/Current_State_Bacula.html>) affect your backup process. From reading that list I believe that bacula would not "work well" in my environment (differential backups). So the following might be very subjective or environment-dependent too. > Has anyone used this device or have another suggestion?

As others already suggested you could try to avoid eSATA and SATA port multipliers by using very large SATA disks and some kind of internal (non-eSATA) enclosure. I don't count eSATA and SATA port multipliers as proven and reliable technology, and I avoid it. > http://www.newegg.com/Product/Product.aspx?Item=N82E16816133001 Some of these comments seem to confirm my feelings. When I needed large capacity externel JBODs I started trying SAS JBODs with SATA disks. I finally bought DELLs MD1000 wit 500GB SATA disks. The enclosures are connected to LSI Logic SAS controllers (3442X-R and 3442E-R), and I run Linux SoftRAID (MD) (so this is at least partially on-topic...) . Works fine now (after I upgraded the LSI controller firmware). At least another well-known vendors offers SAS JBODs (with SATA disks) too (Hewlett-Packard), and some more from small and near-no-name companies.
