New Indexing and Backup Processes Introduced in Ahsay v8.3
Four new processes were introduced in the Ahsay Backup Software v8.3.0.0 (or above) to provide better backup performance, robustness and data integrity:
1. New Index Implementation
Ahsay Backup Software v8.3 has a new index design to provide better backup performance and robustness. However, for customers who are going to upgrade from older versions (v6, v7, and pre-v8.3), they still need to undergo a mandatory index conversion process before the new index can be used and normal backup jobs can continue.
After the v6, v7 and pre-v8.3 AhsayOBM and AhsayACB clients are upgraded to v8.3, the backup set index conversion will occur immediately on the first run of backup job.
1.1 Index Conversion
For AhsayOBM/AhsayACB client
v6 backup sets:
Index.bdb and r-index.bdb will be converted to the new index file structure: index.db* and backupInfo.db*
1. Old index file (index.bdb) will be converted to the new index file structure: (index.db)
2. Data Integrity Check will be performed once the index conversion is finished
v7 and pre-v8.3 backup sets:
index.b2b*, index.xml* and index-s0 will be converted to the new index file structure: index.db* and backupInfo.db*
1. Old index file (index.b2b) will be converted to the new index file structure: (index.db)
2. Data Integrity Check will be performed once the index conversion is finished
For AhsayCBS Run on Server (Office 365 and Cloud File) backup
v7 and pre-v8.3 backup sets:
index.b2b*, index.xml* and index-s0 will be converted to the new index file structure: index.db* and backupInfo.db*
1. Old index file (index.b2b) will be converted to the new index file structure: (index.db)
2. Data Integrity Check will be performed once the index conversion is finished
1.2 Index Conversion requirements
For AhsayOBM/AhsayACB client
| Client Version | Index Conversion Needed | Data Migration Needed |
|---|---|---|
| v6 | ✓ | ✓ |
| v7 | ✓ | X |
| Earlier than v8.3.0.0 | ✓ | X |
| v8.3.0.0 or above | X | X |
Please note:
- Index conversion cannot be disabled.
- For run on client backup sets, index conversion process will automatically start during the first backup job after upgrading AhsayOBM/AhsayACB to v8.3.0.0 or above.
- After index conversion, the size of the index will not be the same. For large data index, the new index will become smaller since duplicate information will be grouped. While for small data index, the new index may be bigger since additional information may be
For AhsayCBS Run on Server (Office 365 and Cloud File) backup
| Client Version | Index Conversion Needed | Data Migration Needed |
|---|---|---|
| v7 | ✓ | X |
| Earlier than v8.3.0.0 | ✓ | X |
| v8.3.0.0 or above | X | X |
Please note:
- For run on server backup sets (Office 365 and Cloud File), index conversion process will automatically start during the first backup job after upgrading AhsayCBS to v8.3.0.0 or above.
