Legacy DS1511+ as a backup NAS for 2 other NAS

[skiboz]

I have a grand workflow / backup plan to use my old very slow DS1511+ 5 bay, purely for daily overnight Hyper Backup of two other NAS' and Time Machine, avoiding high online Cloud backup charges and other benefits.

I will buy a new 8 bay NAS, RS1221RP+ (or hopefully an upgraded RS1223RP+) if I wait for Synology to follow their normal timeline.  I also have a DS716+II 2 bay which will be used primarily for some light Surveillance Station and media storage (I will run a PLEX Server on my intel MacMini)

I will need 30TB maximum for the two full backups some way down the line. The Data Sheet for the DS1511+ from 2011 mentions maximum 5 x 3TB HDD. The Synology Compatibility Chart lists, amongst others; Seagate 6TB Iron Wolf Pro ST6000NE0023 - 2EX110 3.5 Inch HDD SATA 6 Gb/s 7200 RPM 256MB. Also Seagate 10TB Barracuda Pro – 3.5 Inch HDD SATA 6 Gb/s 7200 RPM 256MB.

If anyone has experience, I would be grateful for feedback. can I use 5 x 10TB (Raid 6) Iron Wolf Pro ST10000NE0004 HDD in this old 5 bay? Would I have issues from new HDD firmware or having to use DSM 6.2.4 on the DS1511+ with DSM 7.1.1 on the other two NAS'?

Thanks

It will be easier to use DSM6. There is no drive compatibility limitation introduced. Drives that are not on their compatibility list will very likely work just fine.
DSM7 is where they try to sell their own drives (Toshiba drives) and scare people. But with a few files altered you can also make dsm7 accept all drives.

I hope this helps.

Good to note I have flexibility. What about Hyper Backup? Any issues between DSM6 and DSM7 backup files? Can I Create files targeting a DSM6 Machine and then can the DSM7 machine restore the backup?

Thanks
