incremental errors 0xe00095b3 Unable to create the virtual disk. Using deduplication storage
Hi.
We have strange behavior of BE 2015. Environment:
1. BE2015 server with local disks for local disk-based storage. e:\ f:\ g:\ h:\, each logical volume on one HDD.
installed features: Copy Server Configurations,Virtual Tape Library Support,Deduplication Option,Agent for VMware and Hyper-V,Agent for Applications and Databases.
2. Configured disk based storages in BE2015 using local disks and named:
Deduplication disk storage 0001- H:\BackupExecDeduplicationStorageFolder
Disk storage Full- E:\BEData\
Disk storage inc- G:\BEData\
Duplication storage- F:\BEData\
3. Test server being backed up on ESXi named wksmon01. It is just a regulary flat machine with win7 no additional application on it.
4. Test job which backs up virtual machine wksmon01 with options: GRT (for files) + NBD. Two templates: full - uses "Deduplication disk storage 0001", incremantal- uses "Disk storage inc". One stage: duplicate to disk immediate after full backup uses "Duplication storage".
Let's start action!
а. Full backup- passes with no errors. GRT provide restore individual files.
b. Automatically passes duplication stage. No errors.
c. First Incremental backup- passes. No errors.
d. Remove duplication storage:
- make "Duplication storage" to disabled state
- make disk F:\ offline using disk management console
e. Second incremental backup- ERROR. 0xe00095b3 - Unable to create the virtual disk. Full error text in attach.
After a big series of test jobs with different options and different storage i have that:
Incremental jobs start to fail only after removing "Duplication storage" which was used to duplicate baseline full backup. If i change job option to not using GRT than all subsequent incremental jobs runs fine with no errors even after removing "Duplication storage".
If i use "Deduplication disk storage 0001" for both full and incremental jobs with GRT enabled than all subsequent incremental jobs runs fine wiht no error also.
If i use "Disk storage Full" for full backup and "Disk storage inc" for incremental with GRT enabled i also have no errors with all subsequent incremental jobs even after removing "Duplication storage".
SUMMARY.
incremental jobs with enabled GRT option start to fail after removing "Duplication storage" which was used to copy baseline full backup in case when full backup uses Deduplication disk storage and incremental jobs use Disk storage.
