I try restore broken backup, a lot of errors in firebird.log like this. So a lot of trigger Check_X is broken, when I repair DB, I also delete them when repairing structure of DB.

Database: C:\DATABASE\ERRORDB\MAINBASE.FDB
RDB$FLAGS for trigger CHECK_2791 in RDB$TRIGGERS is corrupted (304)

internal Firebird consistency check (invalid
RDB$CONSTRAINT_TYPE).
Before It gbak retoring this "gbak: restoring privilege for user SYSDBA "
I delete all indexes because I can't activating indexes one by one, and I can't delete them, I can't activating FK, I can activating only PK. I should to delete some FK(about 3 or 5 not more) and indexes from system tables manualy, because I can't delete them by sql.
Because some our consumers is old they using Firebird 2.5.1, other use 2.5.2. I can't see any dependence
between achitecture of
firebird and version of firebird.
Later I try to copy log on validating errors.

WHY? Firebird 2.1 and higher restores all indices it can, and show error on indices that it can't create
(by the PK or FK violation caused by broken records).
So, after restore (without -i) option you just need to check restore
output for errors, then check non-active indices in the DB, and try to
fix data and activate those non-active indices.
