Hi all,

jweiss brought to my attention that you received the last email in error. I=
t is indeed true that TSM is being sunset, and we do need to work through t=
hat transition at some point. However, as the institute provides funding to=
 IS&T to support SIPB, there will be no chargeback.

At this time,  IS&T is still evaluating the best option for these backups. =
We will reach out when we are ready to present the solution we think best a=
nd plan a migration.

Please ignore the deadline stated in the email.

Best,
Robert

Subject: Spectrum Protect (TSM) Sunsetting -- Action Required


Hello,

You are receiving this email because you are associated with machines that =
are actively backing up to Spectrum Protect (TSM). Due to constraints on da=
tacenter space, IS&T is retiring the TSM service. Preparations are being ma=
de to launch a new backup service with a charge-back cost model.

The service is Rubrik NAS-CD<https://www.rubrik.com/solutions/nas> on Amazo=
n S3 Glacier Deep Archive<https://aws.amazon.com/s3/storage-classes/glacier=
/>. It has two charge-back components: a monthly backup/store component and=
 a variable as-used restore component.


Backup/store cost: $7.90/TB/month

Restore cost (estimate): $38/TB

Unfortunately, this pricing is only valid until January 2027 when we expect=
 backup prices to significantly increase. We expect the worst case to be as=
 much as 10x. We are also evaluating a potential CrashPlan solution.

Please let me know ASAP if you are interested in Rubrik or CrashPlan, so I =
can give better pricing updates. Let me know by August 20, 2026 if you are =
committed to moving to Rubrik or have selected another solution. We will th=
en establish a plan and timeline to migrate you off of TSM. You do not need=
 to complete the migration by the mentioned date. However, if I do not hear=
 from you by the mentioned date, your backups may be removed from TSM witho=
ut further warning.

List of machines (apologies if any are missing, all machines backing up to =
TSM are affected): CHARON.MIT.EDU; CHARON4; SIPB-AFS

Best,

Robert
