One thing I’m doing with the new Synology NAS is making sure that everything is successfully migrated from my ancient Infrant ReadyNAS NV+.
There are two basic reasons for this:
The NV+ uses a non-standard power supply, and both of the ones we had at the office eventually burned out, requiring a temporary swap of mine until the data could be retrieved and migrated elsewhere. Mine’s still good, but if it goes…
While the firmware has been updated to cope with the most famous SMB security hole, it’s otherwise an ancient version of Debian on a custom SPARC chip, and even with the RAM upgraded to 1GB, it’s painfully slow at serving up files. It has decent write speeds, but when it comes time to get your terabyte of data back off, it takes forever, especially if you’ve got lots of little files.
I figure the copies should finish by the weekend. Maybe. On the bright side, it’s so slow that the Synology has plenty of bandwidth left to handle copies of every other old drive in the house…
After letting it chug along overnight, it’s averaging a steady 2 MB/s. With 500 GB to go, that’s just about 3 more days. This is so ridiculous that I had to double-check that it really is getting a full-duplex gigabit connection and not falling back to something like 10-megabit/half. No, it’s not the network; it’s just that mind-bogglingly slow. When this is all done, I’m going to reset it to factory defaults and do some testing.
I grabbed a spare 1TB USB drive, formatted it as EXT3, mounted it on the old ReadyNAS, and told it to back up the largest of the volumes (301 GB). It’s rapidly catching up to the aborted rsync job. As a bonus, the built-in backup job uses Perl. 😜
The 301 GB sneakernet finished considerably faster than the rsync job, and my other ReadyNAS just took a few hours, so I now have all my eggs in one basket.
And my basket is now running: find . -not -name '.*' -type f -size +4096 -print0 | xargs -0 md5sum to figure out just how much
duplication there is in the ~6 TB of files (not counting the 2 TB of
Acronis, SuperDuper, and Time Machine images…). I figure there will be
at least six copies of this video:
Update: nine copies of it. 😊
