* Location of home directories.
* Backed up to tape
* Available as the <code>$HOME</code> environment variable.
* Persistent
* Each home directory has a small, fixed [[Storage and file management#Filesystem_Quotas_and_Policies|quota]] of 100GB.
* Not allocated, standard amount for each user. For larger storage requirements, use scratch or project.
* Has daily backup.

* For active or temporary (<code>/scratch</code>) storage (~ 80 GB/s).
* Inactive data is purged.
* Available as the <code>$SCRATCH</code> environment variable.
* Not allocated.
* Large fixed [[Storage and file management#Filesystem_Quotas_and_Policies|quota]] per user and per group path.
* Inactive data will be purged.

| '''Burst buffer'''<br>232TB (~160GB/s)<br>Parallel extra high-performance filesystem (Excelero+IBM Spectrum Scale)||
* For active fast storage during a job (160GB/s, and very high IOPS).
* Inactive data is purged.
* Not fully configured yet, but data will be purged very frequently (i.e. soon after a job has ended) and space on this storage tier will not be RAC allocatable.

* Backed up to tape
* For active but low data turnover storage and relatively fixed datasets
* Allocated through [https://www.computecanada.ca/research-portal/accessing-resources/resource-allocation-competitions RAC]

* Allocated via [https://www.computecanada.ca/research-portal/accessing-resources/resource-allocation-competitions/ RAC].
* tape-backed HSM
* Nearline accessible space intended for large datasets requiring offload from active filesystems.
* Allocated through [https://www.computecanada.ca/research-portal/accessing-resources/resource-allocation-competitions RAC]
* Available as the <code>$ARCHIVE</code> environment variable.
* Persistent
* Large fixed [[Storage and file management#Filesystem_Quotas_and_Policies|quota]] per group.
* Tape based backend (dual copy).
