Thank you for using Surusu.

As you may be aware, Surusu has up until now had periodic 15~20-minute service interruptions while backups are taken.

Wanting to eliminate the need to interrupt service in order to take a backup, today I started working with a “live backup” solution.

Unfortunately and quite ironically, this “live backup” solution led to the loss of the very user data — yours and mine — that it was intended to protect.

Fortunately, I had taken a full, “normal” backup just one week ago.
It has become necessary to restore this week-old backup.
As a result, one week’s worth of entered cards [anything entered between September 12 and September 20 (Japan time)] have been lost, and may not be recoverable. Repetition data has also been reset to September 12 status, although this does not represent a significant problem since it will just mean extra review.

Your time and data are valuable.
I apologize deeply for the inconvenience.
I shall continue to work to find stable, sustainable ways to ensure the integrity of the system.
For now, that may mean the occasional 15~20 minute service interruption while a very pedestrian backup is taken.

The Good News

The Surusu interface has been updated extensively for even more pleasant use. There have also been dozens of back-end fixes. Notably, the sporadic problem with “Extra Reps” processing not going through, has been repaired.

Thank you again for using Surusu.

Best regards,

Khatzumoto

[P.S.]: Will This Sort of Thing Happen Again?

No.

This was the first Surusu data loss incident of any kind in all its nearly 4 years of operation. And the fault was ultimately human error — mine. At the time, I was in a rush to get cool new stuff working “invisibly”, with minimum inconvenience to everyone else.

The webhost/server is one of the best out there…the database system is stable…the programmer was in too much of a hurry 😀 . A deliberate pace and simple safety checks, as has been the usual policy, can and will prevent all loss of this kind.

The immediate short-term direction is more frequent backups. Beyond that, adding functionality so we can all download and back-up our data locally is a high priority, something I want to add as soon as possible.

So, both as a user and a programmer…I’ll do my very best and more. Your concern is completely warranted, and I feel your pain — my data, all 25000 odd cards and  nearly 100000 reps — are in there, too 😀 .

Deepest apologies again for the inconvenience 🙂 .
