About NetBackup for SQL Server backup names
The backup name is a string that consists of the following components. These components are separated by a delimiter that is specified by the character that precedes the "C" at the end of the backup image name.
1 - Named instances are formatted as <host>\<instance-name>. The default instance is the name of the host machine.
2 - The object types are as follows:
db | database |
inc | database differential |
trx | transaction log |
fg | filegroup |
fgd | filegroup differential |
fil | file |
3 - The name of the file or filegroup if the object type is a file or filegroup; otherwise the symbol ~ is used.
4 - The block size.
5 - Stripes are specified as <stripe number>of<total stripes>. non-striped backups are always 001of001. For striped backups, <total stripes> is the total number of stripes for the backup. <stripe number> is the count number of the backup for that backup, starting with 001.
6 - The format of the timestamp is YYYYMMDDHHMMSS. The timestamp for AG backup images reflects Coordinated Universal Time (UTC). For non-AG backup images, the timestamp reflects the time zone that is configured for the NetBackup server.
7 - The delimiter, which immediately precedes the version indicator. For non-AG database images, this character is a period (.) by default. For AG database images, the character is a forward slash (/). However, if a period or slash is used in any of the fields, the delimiter may be another character.
8 - "C" is applied to all SQL Server backup image names, regardless of the NetBackup version.
9 - Backup images for AG databases are formatted as <WindowsServerFailoverCluster>:<nodename>/MSSQL7/<AGname>.
