comment btrfs-enabled backup solution
@unhammer: using rsync without --inplace you'll get multiple copies of the same data in the remote file system. (rsync normally copies data to a temporary hidden file and then moves it over the old file, with a Copy-On-Write file system you get two copies on unchanged data this way)

comment RAID 6 vs RAID 10? Which would you choose
While RAID10 usually is built using only 2-drive RAID1 pairs, it's not always the case. Linux mdadm allows to create a RAID10 layout with any level of redundancy (2, 3, 4,...), as long as its lower than the number of drives in array (so it's possible to create a RAID10 with two copies of data with only 3 drives). The --layout= option allows to set number of copies.

comment Restricted LDAP mimic server backed on SQL
OpenLDAP does support backend sql but it is full fledged, not a simple mapper. If you really don't want to manage two user stores, I'd guess that making PostgreSQL use LDAP for authentication will be easier. You also have to remember that lots of software do use group membership to decide whatever to authenticate user or not...

comment Does the Windows Server 2012 Data Deduplication feature work with 3rd party defrag programs?
I'm quite sure that you won't loose any data, the bigger question is whatever the data will remain deduplicated. Deduplication usually causes quite high fragmentation...

comment How is memory usage reported in Linux?
Shared size is memory that may be shared. If an application is sole user of library the library will be kept in memory by single process. This way even shared memory can be "process owned" memory.

comment Failing Sata HDD
@ProBackup: for those two SMART values you want to look at RAW_VALUE, if it is non-zero, it means the drive is failing. Any value over 10 means the drive is long dead. Current_Pending_Sector sometimes can be "fixed" by performing read and write on the failing sector (LBA_of_first_error can be helpful in this regard).
